再调节电位器Rw。

当将电位器Rw调节到最大值时,测量输出电压达到限定范围的最小值,此时Uo为6V左右,如图6所示;当将电位器Rw调节到最小值时,测量输出电压达到限定范围的最大值,此时Uo为15V左右,如图7所示,即满足稳压电源输出直流可调电压6V<Uo<15V这一技术指标的要求。

该过程中如不满足要求,可适当调整R1、R2的值。

This means that switch duty cycle is directly controlled by switch current rather than by output voltage. Referring to the block diagram, the switch is turned “on” at the start of each oscillator cycle. It is turned “off” when switch current reaches a predetermined level. Control of output voltage is obtained by using the output of a voltage sensing error amplifier to set current trip level. This technique has several advantages. First, it has immediate response to input voltage variations, unlike ordinary switchers which have notoriously poor line transient response. Second, it reduces the 90 phase shift at midfrequencies in the energy storage inductor. This greatly simplifies closed loop fre-quency compensation under widely varying input voltage or output load conditions. Finally, it allows simple pulse-by-pulse current limiting to provide maximum switch protection under output overload or short conditions. A low-dropout internal regulator provides a 2.3V supply for all internal circuitry on the LT1072. This low-dropout design allows input voltage to vary from 3V to 60V with virtually no change in device performance. A 40kHz oscillator is the basic clock for all internal timing. It turns “on” the output switch via the logic and driver circuitry. Special adaptive antisat circuitry detects onset of saturation in the power switch and adjusts driver current instantaneously to limit switch saturation. This minimizes driver dissipation and provides very rapid turn-off of the switch.A 1.2V bandgap reference biases the positive input of the error amplifier. The negative input is brought out for output voltage sensing. This feedback pin has a second function; when pulled low with an external resistor, it programs the LT1072 to disconnect the main error amplifier output and connects the output of the flyback amplifier to the comparator input. The LT1072 will then regulate the value of the flyback pulse with respect to the supply voltage. This flyback pulse is directly proportional to output voltage in the traditional transformer coupled flyback topology regulator. By regulating the amplitude of the flyback pulse, the output voltage can be regulated with no direct connection between input and output. The output is fully floating up to the breakdown voltage of the transformer windings. Multiple floating outputs are easily obtained with additional windings. A special delay network inside the LT1072 ignores the leakage inductance spike at the leading edge of the flyback pulse to improve output regulation.The error signal developed at the comparator input is brought out externally. This pin (V C) has four different functions. It is used for frequency compensation, current limit adjustment, soft starting, and total regulator shutdown. During normal regulator operation this pin sits at a voltage between 0.9V (low output current) and 2.0V (high output current). The error amplifiers are current output (gm) types, so this voltage can be externally clamped for adjusting current limit. Likewise, a capacitor coupled external clamp will provide soft start. Switch duty cycle goes to zero if the V C pin is pulled to ground through a diode, placing the LT1072 in an idle mode. Pulling the V C pin below 0.15V causes total regulator shutdown, with only 50µA supply current for shutdown circuitry biasing. See AN-19 for full application details.Extra Pins on the MiniDIP and Surface Mount Packages The 8 and 16-pin versions of the LT1072 have the emitters of the power transistor brought out separately from the ground pin. This eliminates errors due to ground pin voltage drops and allows the user to reduce switch current limit 2:1 by leaving the second emitter (E2) disconnected. The first emitter (E1) should always be connected to the ground pin. Note that switch “on” resistance doubles when E2 is left open, so efficiency will suffer somewhat when switch currents exceed 100mA. Also, note that chip dissipation will actually increase with E2 open during normal load operation, even though dissipation in current limit mode will decrease. See “Thermal Considerations.”Thermal Considerations When Using Small Packages The low supply current and high switch efficiency of the LT1072 allow it to be used without a heat sink in most applications when the TO-220 or TO-3 package is selected. These packages are rated at 50°C/W and 35°C/W respectively. The small packages, however, are rated at greater than 100°C/W. Care should be taken with these packages to ensure that the worse case input voltage and load current conditions do not cause excessive die temperatures. The following formulas can be used as aLT1072 OPERATIO71072fcrough guide to calculate LT1072 power dissipation. For more details, the reader is referred to Application Note 19 (AN19), “Efficiency Calculations” section.Average supply current (including driver current) is:I IN≈ 6mA + I SW(0.004 + DC/40)I SW = switch currentDC = switch duty cycleSwitch power dissipation is given by:P SW = (I SW)2 • R SW • DCR SW = LT1072 switch “on” resistance (1Ω maximum) Total power dissipation is the sum of supply current times input voltage plus switch power:P TOT = (l lN)(V IN) + P SWIn a typical example, using a boost converter to generate *********************,dutycycleisapproximately 60%, and switch current is about 0.65A, yielding:l lN = 6mA + 0.65(0.004 + DC/40) = 18mAP SW = (0.65)2 • 1Ω • (0.6) = 0.25WP TOT = (5V)(0.018A) + 0.25 = 0.34W Temperature rise in a plastic miniDIP would be 130°C/W times 0.34W, or approximately 44°C. The maximum ambient temperature would be limited to 100°C (commercial temperature limit) minus 44°C, or 56°C.In most applications, full load current is used to calculate die temperature. However, if overload conditions must also be accounted for, four approaches are possible. First, if loss of regulated output is acceptable under overload conditions, the internal thermal limit of the LT1072 will protect the die in most applications by shutting off switch current. Thermal limit is not a tested parameter, however, and should be considered only for non-critical applications with temporary overloads. A second approach is to use the larger TO-220 (T) or TO-3 (K) package which, even without a heat sink, may limit die temperatures to safe levels under overload conditions. In critical situations, heat sinking of these packages is required; especially if overload conditions must be tolerated for extended periods of time.The third approach for lower current applications is to leave the second switch emitter open. This increases switch “on” resistance by 2:1, but reduces switch current limit by 2:1 also, resulting in a net 2:1 reduction in I2R switch dissipation under current limit conditions.The fourth approach is to clamp the V C pin to a voltage less than its internal clamp level of 2V. The LT1072 switch current limit is zero at approximately 1V on the V C pin and 2A at 2V on the V C pin. Peak switch current can be externally clamped between these two levels with a diode. See AN-19 for details.LT1072 SynchronizingThe LT1072 can be externally synchronized in the frequency range of 48kHz to 70kHz. This is accomplished as shown in the accompanying figures. Synchronizing occurs when the V C pin is pulled to ground with an external transistor. To avoid disturbing the DC characteristics of the internal error amplifier, the width of the synchronizing pulse should be under 1µs. C2 sets the pulse width at ≈ 0.35µs. The effect of a synchronizing pulse on the LT1072 amplifier offset can be calculated from:KT=26mV at 25°Cqt S=pulse widthf S=pulse frequencyI C=LT1072 V C source current (≈ 200µA)V C=LT1072 operating V C voltage (1V to 2V)R3=resistor used to set mid-frequency “zero” in LT1072 frequency compensation network.With t S = 0.35µs, f S = 50kHz, V C = 1.5V, and R3 = 2KΩ, offset voltage shift is ≈2.2mV. This is not particularly bothersome, but note that high offsets could result if R3 were reduced to a much lower value. Also, the synchronizing transistor must sink higher currents with low values of R3, so larger drives may have to be used. The transistor must be capable of pulling the V C pin to within 200mV of ground to ensure synchronizing.LT1072 OPERATIO∆V OS =(t S)(f S) I C +I CKTq(((V CR3(81072fc91011121314Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

一、产品概述市场中的节电装置大都不具备稳压的功能,仅仅降低装置的供电电压,从而达到节电的目的。

其弊端为:当电网电压稍有波动时,装置的输出电压升高,不再节电;或者输出电压降得更低,对负载的影响较大。

由此可见,稳压功能是节电装置必备的一项功能,也是能够实现节电的必要条件。

LH-100型智能节电装置根据用户电网电压的波动情况、照明负载的性质,为负载提供稳定的供电电压。

用户可根据需求,设置输出电压,对负载的运行时间和供电方式进行编程,最大限度地降低负载的电耗。

若不计补偿变压器阻抗压降,则从图二可见:Uao=Uai+Uac式中:Uai—稳压器A相输入电压;Uao—稳压器A相输出电压;Uac—稳压器A相补偿电压;图二单相补偿电力原理图其原理是:当A相输入电压Uai增加ΔUai时,补偿电压Uac也相应改变ΔUac且ΔUac=-ΔUai时,使A相输出电压Uao保持不变,同理B相、C相也是如此。

其稳压调压过程是:根据输出电压的变化,由电压检测单元采样,检测并输出信号控制电动机SM转动,经减速机构并有链条带动调压变压器TUV上的电刷组滑动(或滚动)来调节调压器的第二次电压,以改变补偿电压的极性和大小,降低或升高输出电压,进而达到节电的目的。
