摘要

传统 DPWM 方法的开关损耗较大。因此,本文改进了传统的 DPWM 方法,增加了一个箝位区间,以降低开关损耗。同时还利用调制波形空间重组方法对传统方法进行了改进,改进了加入箝位区间的调制信号,使每个开关的开关频率保持一致,从而平衡了级联 H 桥多级逆变器中每个 H 桥单元的开关损耗,提高了逆变器的可靠性。采用载波移相方法实现了每个 H 桥单元的功率平衡。仿真和实验结果验证了调制策略的可行性。

Improved DPWM modulation for reducing switching losses in cascaded H-bridge multilevel inverters

The switching loss of the traditional DPWM method is large. Therefore, this paper improves the traditional DPWM method by adding a clamping interval to reduce the switching loss. The traditional method is also improved using a modulating waveform spatial reorganization method to improve the modulation signal added to the clamping interval so that the switching frequency of each switch remains consistent, which balances the switching loss of each H-bridge unit of the cascaded H-bridge multilevel inverter and improves the reliability of the inverter. The carrier phase-shifting method is used to realize the power balance of each H-bridge unit. Simulation and experimental results verify the feasibility of the modulation strategy.
