ZHCS012A–SEPTEMBER2011–REVISED SEPTEMBER2011DEVICE INFORMATIONTerminal FunctionsTERMINALDESCRIPTIONNAME NO.The position decoder logic translates the Hall signals and the DIR signal to the correct driversignals(PUs and PDs).To prevent output stage damage,the signal on DIR is first loadedinto a direction latch,then shifted through a two-bit register.As long as SPEED-IN is less than250mV,the direction latch is transparent.WhenSPEED-IN is higher than250mV,the direction latch inhibits all changes indirection.SPEED-IN can be connected to TACH-OUT through a filter,so that the direction latch is onlytransparent when the motor is spinning slowly,and has too little stored energy to damagepower devices.Additional circuitry detects when the input and output of the direction latch are different,or DIR,SPEED-IN6,7when the input and output of the shift register are different,and inhibits all output drivesduring that time.This can be used to allow the motor to coast to a safe speed beforereversing.The shift register ensures that direction can not be changed instantaneously.The register isclocked by the PWM oscillator,so the delay between direction changes is always going to bebetween one and two oscillator periods.At40kHz,this corresponds to a delay of between25μs and50μs.Regardless of output stage,25μs deadtime should be adequate to ensureno overlap cross-conduction.Toggling DIR causes an output pulse on TACH-OUTregardless of motor speed.E/A IN(+)and E/A IN(–)are not internally committed to allow for a wide variety of uses.Theycan be connected to the ISENSE,to TACH-OUT through a filter,to an external commandvoltage,to a D/A converter for computer control,or to another op amp for more elegantfeedback loops.The error amplifier is compensated for unity gain stability,so E/A OUT canbe tied to E/A IN(–)for feedback and major loop compensation.E/A IN(+),E/A IN(–),E/A1,28,27,26E/A OUT and PWM In drive the PWM comparator.For voltage-mode PWM systems,PWM In OUT,PWM INcan be connected to RC-OSC.The PWM comparator clears the PWM latch,commandingthe outputs to chop.The error amplifier can be biased off by connecting E/A IN(–)to a higher voltage than/EAIN(+).When biased off,E/A OUT appears to the application as a resistor to ground.E/A OUTcan then be driven by an external amplifier.GND15All thresholds and outputs are referred to the GND pin except for the PD and PU outputs.The three shaft position sensor inputs consist of hysteresis comparators with input pullupresistors.Logic thresholds meet TTL specifications and can be driven by5-V CMOS,12-VCMOS,NMOS,or open-collectors.Connect these inputs to motor shaft position sensors that are positioned120electricaldegrees apart.If noisy signals are expected,zener clamp and filter these inputs with6-VH1,H2,H38,9,10zeners and an RC filter.Suggested filtering components are1kΩand2nF.Edge skew inthe filter is not a problem,because sensors normally generate modified gray code with onlyone output changing at a time,but rise and fall times must be shorter than20μs for correcttachometer operation.Motors with60electrical degree position sensor coding can be used ifone or two of the position sensor signals is inverted.The current sense amplifier has a fixed gain of approximately two.It also has a built-in levelshift of approximately2.5V.The signal appearing on ISENSE is:I SENSE=2.5V+(2×ABS(I SENSE1–I SENSE2))I SENSE1and I SENSE2are interchangeable and can be used as differential inputs.Thedifferential signal applied can be as high as±0.5V before saturation.If spikes are expected on ISENSE1or ISENSE2,they are best filtered by a capacitor fromISENSE to ground.Filtering this way allows fast signal inversions to be correctly processed ISENSE1,ISENSE2,by the absolute value circuit.The peak-current comparator allows the PWM to enter a3,4,5ISENSE current-limit mode with current in the windings never exceeding approximately0.2V/R SENSE.The overcurrent comparator provides a fail-safe shutdown in the unlikely case ofcurrent exceeding0.3V/R SENSE.Then,softstart is commanded,and all outputs are turnedoff until the high current condition is removed.It is often essential to use some filter drivingISENSE1and ISENSE2to reject extreme spikes and to control slew rate.Reasonablestarting values for filter components might be250-Ωseries resistors and a5-nF capacitorbetween ISENSE1and ISENSE2.Input resistors should be kept small and matched tomaintain gain accuracy.This input can be used as an over-voltage shut-down input,as a coast input,or both.ThisOV-COAST23input can be driven by TTL,5-V CMOS,or12-V CMOS.UC1625-SPZHCS012A–SEPTEMBER2011–REVISED Terminal Functions(continued)TERMINALDESCRIPTIONNAME NO.These outputs can drive the gates of N-channel power MOSFETs directly or they can drivethe bases of power Darlingtons if some form of current limiting is used.They are meant todrive low-side power devices in high-current output stages.Current available from these pins PDA,PDB,PDC12,13,14can peak as high as0.5A.These outputs feature a true totem-pole output stage.Beware ofexceeding device power dissipation limits when using these outputs for high continuouscurrents.These outputs pull high to turn a“low-side”device on(active high).These outputs are open-collector,high-voltage drivers that are meant to drive high-sidepower devices in high-current output stages.These are active low outputs,meaning thatthese outputs pull low to command a high-side device on.These outputs can drivePUA,PUB,PUC16,17,18low-voltage PNP Darlingtons and P-channel MOSFETs directly,and can drive anyhigh-voltage device using external charge pump techniques,transformer signal coupling,cascode level-shift transistors,or opto-isolated drive(high-speed opto devices arerecommended).(See applications).This supply pin carries the current sourced by the PD outputs.When connecting PD outputsdirectly to the bases of power Darlingtons,the PWR VCC pin can be current limited with a PWR VCC11resistor.Darlington outputs can also be"Baker Clamped"with diodes from collectors back toPWR VCC.(See Applications)The device can chop power devices in either of two modes,referred to as“two-quadrant”(Quad Sellow)and“four quadrant”(Quad Sel high).When two-quadrant chopping,thepulldown power devices are chopped by the output of the PWM latch while the pullup driversremain on.The load chops into one commutation diode,and except for back-EMF,willexhibit slow discharge current and faster charge current.Two-quadrant chopping can be QUAD SEL22more efficient than four-quadrant.When four-quadrant chopping,all power drivers are chopped by the PWM latch,causing theload current to flow into two diodes during chopping.This mode exhibits better control of loadcurrent when current is low,and is preferred in servo systems for equal control overacceleration and deceleration.The QUAD SEL input has no effect on operation duringbraking.Each time the TACH-OUT pulses,the capacitor tied to RC-BRAKE discharges fromapproximately3.33V down to1.67V through a resistor.The tachometer pulse width isapproximately T=0.67R T C T,where R T and C T are a resistor and capacitor fromRC-BRAKE to ground.Recommended values for R T are10kΩto500kΩ,andrecommended values for C T are1nF to100nF,allowing times between5μs and10ms.Best accuracy and stability are achieved with values in the centers of those ranges.RC-BRAKE also has another function.If RC-BRAKE pin is pulled below the brake threshold, RC-BRAKE21the device enters brake mode.This mode consists of turning off all three high-side devices,enabling all three low-side devices,and disabling the tachometer.The only things that inhibitlow-side device operation in braking are low-supply,exceeding peak current,OV-COASTcommand,and the PWM comparator signal.The last of these means that if current sense isimplemented such that the signal in the current sense amplifier is proportional to brakingcurrent,the low-side devices will brake the motor with current control.(See applications)Simpler current sense connections results in uncontrolled braking and potential damage tothe power devices.The UC1625can regulate motor current using fixed-frequency pulse width modulation(PWM).The RC-OSC pin sets oscillator frequency by means of timing resistor R OSC from theRC-OSC pin to VREF and capacitor COSC from RC-OSC to Gnd.Resistors10kΩto100kΩand capacitors1nF to100nF works the best,but frequency should always be below500kHz.Oscillator frequency is approximately:F=2/(R OSC x C OSC)RC-OSC25Additional components can be added to this device to cause it to operate as a fixed off-timePWM rather than a fixed frequency PWM,using the RC-OSC pin to select the monostabletime constant.The voltage on the RC-OSC pin is normally a ramp of about1.2V peak-to-peak,centered atapproximately1.6V.This ramp can be used for voltage-mode PWM control,or can be usedfor slope compensation in current-mode control.O n T i m eC T –m F1 m 10 m 100 m100 Hz1 kHz 10 kHz100 kHz 1 MHzO s c i l l a t o r F r e q u e n c yC OSC (m F)UC1625-SPZHCS012A –SEPTEMBER 2011–REVISED SEPTEMBER 2011Terminal Functions (continued)TERMINAL DESCRIPTIONNAMENO.Any time that VCC drops below threshold or the sensed current exceeds the over-current threshold,the soft-start latch is set.When set,it turns on a transistor that pulls down on SSTART.Normally,a capacitor is connected to this pin,and the transistor will completely discharge the capacitor.A comparator senses when the NPN transistor has completely discharged the capacitor,and allows the soft-start latch to clear when the fault is removed.When the fault is removed,the soft-start capacitor charges from the on-chip current source.SSTART clamps the output of the error amplifier,not allowing the error amplifier output SSTART 24voltage to exceed SSTART regardless of input.The ramp on RC-OSC can be applied to PWM In and compared to E/A OUT.With SSTART discharged below 0.2V and the ramp minimum being approximately 1.0V,the PWM comparator keeps the PWM latch cleared and the outputs off.As SSTART rises,the PWM comparator begins to duty-cycle modulate the PWM latch until the error amplifier inputs overcome the clamp.This provides for a safe and orderly motor start-up from an off or fault condition.A 51-k Ωresister is added between VREF and SSTART to ensure switching.Any change in the H1,H2,or H3inputs loads data from these inputs into the position sensor latches.At the same time data is loaded,a fixed-width 5-V pulse is triggered on TACH-OUT.The average value of the voltage on TACH-OUT is directly proportional to speed,so this output can be used as a true tachometer for speed feedback with an external filter or TACH-OUT 20averaging circuit which usually consists of a resistor and capacitor.Whenever TACH-OUT is high,the position latches are inhibited,such that during the noisiest part of the commutation cycle,additional commutations are not possible.Although this effectively sets a maximum rotational speed,the maximum speed can be set above the highest expected speed,preventing false commutation and chatter.This device operates with supplies between 10V and 18V.Under-voltage lockout keeps all outputs off below 7.5V,insuring that the output transistors never turn on until full drive VCC 19capability is available.Bypass VCC to ground with an 0.1-μF ceramic ing a 10-μF electrolytic bypass capacitor as well can be beneficial in applications with high supply impedance.This pin provides regulated 5V for driving Hall-effect devices and speed control circuitry.VREF reaches 5V before VCC enables,ensuring that Hall-effect devices powered from VREF 2VREF becomes active before the UC1625drives any output.For proper performance VREF should be bypassed with at least a 0.1-μF capacitor to ground.TYPICAL CHARACTERISTICSOscillator FrequencyTachometer on Timevsvs C OSC and R OSCRT

PreventionThe UC1625inserts delays to prevent cross conduction due to overlapping drive signals.However,some thought must always be given to cross conduction in output stage design because no amount of dead time can prevent fast slewing signals from coupling drive to a power device through a parasitic capacitance.The UC1625contains input latches that serve as noise blanking filters.These latches remain transparent through any phase of a motor rotation and latch immediately after an input transition is detected.They remain latched for two cycles of the PWM oscillator.At a PWM oscillator speed of 20kHz,this corresponds to 50μs to 100μs of blank time which limits maximum rotational speed to 100kRPM for a motor with six transitions per rotation or 50kRPM for a motor with 12transitions per rotation.This prevents noise generated in the first 50μs of a transition from propagating to the output transistors and causing cross-conduction or chatter.The UC1625also contains six flip flops corresponding to the six output drive signals.One of these flip flops is set every time that an output drive signal is turned on,and cleared two PWM oscillator cycles after that drive signal is turned off.The output of each flip flop is used to inhibit drive to the opposing output (Figure 8).In this way,it is impossible to turn on driver PUA and PDA at the same time.It is also impossible for one of these drivers to turn on without the other driver having been off for at least two PWM oscillator clocks.Figure 8.Cross Conduction PreventionUC1625-SPZHCS012A–SEPTEMBER2011–REVISED Power Stage DesignThe UC1625is useful in a wide variety of applications,including high-power in robotics and machinery.The power output stages used in such equipment can take a number of forms,according to the intended performance and purpose of the system.Figure9show four different power stages with the advantages and disadvantages of each.For high-frequency chopping,fast recovery circulating diodes are essential.Six are required to clamp the windings.These diodes should have a continuous current rating at least equal to the operating motor current, since diode conduction duty-cycle can be high.For low-voltage systems,Schottky diodes are preferred.In higher voltage systems,diodes such as Microsemi UHVP high voltage platinum rectifiers are recommended.In a pulse-by-pulse current control arrangement,current sensing is done by resistor R S,through which the transistor's currents are passed(Fig.A,B,and C).In these cases,R D is not needed.The low-side circulating diodes go to ground and the current sense terminals of the UC1625(I SENSE1and I SENSE2)are connected to R S through a differential RC filter.The input bias current of the current sense amplifier causes a common mode offset voltage to appear at both inputs,so for best accuracy,keep the filter resistors below2kΩand matched. The current that flows through R S is discontinuous because of chopping.It flows during the on time of the power stage and is zero during the off time.Consequently,the voltage across R S consists of a series of pulses, occurring at the PWM frequency,with a peak value indicative of the peak motor current.To sense average motor current instead of peak current,add another current sense resistor(R D in Fig.D)to measure current in the low-side circulating diodes,and operate in four quadrant mode(pin22high).The negative voltage across R D is corrected by the absolute value current sense amplifier.Within the limitations imposed by Table2,the circuit of Fig.B can also sense average current.TOMOTORFIGURE ATOMOTORFIGURE BTOMOTORFIGURE CTOMOTORFIGURE DUC1625-SPZHCS012A –SEPTEMBER 2011–REVISED SEPTEMBER 2011Figure 9.Four Power Stage Designs Table 2.Imposed Limitations for Figure 9CURRENT SENSESAFE 2QUADRANT4QUADRANTPOWER REVERSEBRAKINGPulse-by-PulseAverage Figure A Yes No No N0Yes No Figure B Yes Yes No In 4-quad mode only Yes Yes Figure C Yes Yes Yes In 4-quad mode only Yes No Figure DYesYesYesIn 4-quad mode onlyYesYesUC1625-SPZHCS012A –SEPTEMBER 2011–REVISED SEPTEMBER 2011For drives where speed is critical,P-channel MOSFETs can be driven by emitter followers as shown in Figure 10.Here,both the level shift NPN and the PNP must withstand high voltages.A zener diode is used to limit gate-source voltage on the MOSFET.A series gate resistor is not necessary,but always advisable to control overshoot and ringing.High-voltage optocouplers can quickly drive high-voltage MOSFETs if a boost supply of at least 10V greater than the motor supply is provided (See Figure 11)To protect the MOSFET,the boost supply should not be higher than 18V above the motor supply.For under 200-V 2-quadrant applications,a power NPN driven by a small P-Channel MOSFET performs well as a high-side driver as in Figure 12.A high voltage small-signal NPN is used as a level shift and a high voltage low-current MOSFET provides drive.Although the NPN does not saturate if used within its limitations,the base-emitter resistor on the NPN is still the speed-limiting component.Figure 13shows a power NPN Darlington drive technique using a clamp to prevent deep saturation.By limiting saturation of the power device,excessive base drive is minimized and turn-off time is kept fairly ck of base series resistance also adds to the speed of this approach.Figure 10.Fast High-Side P-Channel DriverFigure 11.Optocoupled N-Channel High-SideDriverUC1625-SP ZHCS012A–SEPTEMBER2011–REVISED SEPTEMBER2011Figure12.Power NPN High-Side Driver Figure13.Power NPN Low-Side DriverUC1625-SPZHCS012A–SEPTEMBER2011–REVISED Fast High-Side N-Channel Driver with Transformer IsolationA small pulse transformer can provide excellent isolation between the UC1625and a high-voltage N-Channel MOSFET while also coupling gate drive power.In this circuit(shown in Figure14),a UC3724is used as a transformer driver/encoder that duty-cycle modulates the transformer with a150-kHz pulse train.The UC3725 rectifies this pulse train for gate drive power,demodulates the signal,and drives the gate with over2-A peak current.Figure14.Fast High-Side N-Channel Driver with Transformer IsolationBoth the UC3724and the UC3725can operate up to500kHz if the pulse transformer is selected appropriately. To raise the operating frequency,either lower the timing resistor of the UC3724(1kΩmin),lower the timing capacitor of the UC3724(500pF min)or both.If there is significant capacitance between transformer primary and secondary,together with very high output slew rate,then it may be necessary to add clamp diodes from the transformer primary to12V and ground. General purpose small signal switching diodes such as1N4148are normally adequate.The UC3725also has provisions for MOSFET current limiting.See the UC3725data sheet for more information on implementing this.UC1625-SP ZHCS012A–SEPTEMBER2011–REVISED SEPTEMBER2011Computational Truth TableTable3shows the outputs of the gate drive and open collector outputs for given hall input codes and direction signals.Numbers at the top of the columns are pin numbers.These devices operate with position sensor encoding that has either one or two signals high at a time,never all low or all high.This coding is sometimes referred to as"120°Coding"because the coding is the same as coding with position sensors spaced120magnetic degrees about the rotor.In response to these position sense signals, only one low-side driver turns on(go high)and one high-side driver turns on(pull low)at any time.putational Truth TableINPUTS OUTPUTSDIR H1H2H3Low-Side High-Side68910121314161718 1001L H L L H H 1011L L H L H H 1010L L H H L H 1110H L L H L H 1100H L L H H L 1101L H L H H L 0101L L H H L H 0100L L H L H H 0110L H L L H H 0010L H L H H L 0011H L L H H L 0001H L L H L H X111L L L H H H X000L L L H H H。

4.基本工作原理：JD1A—40电磁调速电动机控制装置是由速度调节器、移相触发器、可控硅整流电路及速度负反馈等环节所组成。
图1为装置原理方框图。
图2为装置的电气原理图。
图3为装置的移相触发各点波形图。
从图1-图4可知，二种线路的工作原理都是相同的。
速度指令信号电压和调速负反馈信号电压比较后，其差值信号被送入速度调节器（或前置放大器）进行放大，放大后的信号电压与锯齿波叠加，控制了晶体管的导通时刻，产生了随着差值信号电压改变而移动的脉冲，从而控制了可控硅的开放角，使滑差离合器的激磁电流得到了控制，即滑差离合器的转速随着激磁电流的改变而改变。
由于速度负反馈的作用，使电磁调速电动机实现恒转矩无极调速。
从图2-图3可知，JD1A—40型的速度指令信号电压是由装在控制箱面板上的速度操作电位器产生的。
