曾江,等:考虑中点电位平衡的三电平 Boost-逆变器协调控制
(School of Electric Power,South China University of Technology,Guangzhou 510640,Guangdong,China)
Abstract: In order to reduce the switching loss of the inverter and control the neutral-point potential balance,a novel discontinuous space vector modulation was proposed for the typical two stage TL- Boost converter and threelevel inverter. Based on charge balance principle,the charge compensation of the TL-Boost converter was quantitatively calculated,and the adjustment of duty ratio was deduced,the total amount of charge flowing through the neutral-point was controlled to be zero. Through the coordinated control strategy of two stage,not only the advantage of the lowswitching loss of the discontinuous modulation could be play,but also the neutral- point potential fluctuations was suppressed,and modulation complexity of inverter was reduced. Finally,the effectiveness of the control strategy was
