摘要

采用相移脉宽调制(PS-PWM)的级联h桥逆变器是集成不同性质的直流电源的一种有吸引力的选择。非等直流电源通过引入不希望的低频次谐波而损害电流总谐波失真(THD)。本文提出，对于超过3个h桥，在PWM周期内存在两种独特的电流总谐波失真(THD)极值直流源开关序列——最好的是最小化不需要的低频电流谐波含量(最小THD)，最差的是提供最大电流THD。这些极端序列完全依赖于直流电源电压不等关系。

On Current THD Extreme Switching Sequences for a Single-Phase Cascade H-Bridge Inverter with Phase-Shifted PWM and Non-Equal DC Sources

Cascade H-bridge inverter with Phase-Shifted Pulse Width Modulation (PS-PWM) is an attractive choice for integration of DC sources of different nature. Non-equal DC sources compromise current Total Harmonic Distortion (THD) by introducing undesirable low frequency subharmonics. This paper suggests that, for more than 3 H-bridges, there are two unique current Total Harmonic Distortion (THD) extreme DC source switching sequences on a PWM period-the best that minimizes undesirable low frequency current harmonic content (minimal THD) and the worst that delivers maximal current THD. These extreme sequences depend solely on DC source voltage inequality relationships.
