一种三相五电平电流型变流器和基于多载波的PWM研究

Research on Three-phase Five-level Current Source Inverter and Muiticarrier PWM Techniques

分析了一种电流型5电平逆变器拓扑,并介绍了几种适用于电流型变流器的调制方式,用PD、POD、APOD、载波带频率变化的PWM方法对相关的拓扑进行了仿真分析,并比较了它们各自的特点。

The several CSI＇s PWM control strategies are presented .The three-phase multilevel current source inverter topology is simulated by the PD,POD,APOD PWM control strategies and merits and faults are studied at the same time.
