基于模块化多电平变换器与并联混合变换器的开口绕组交流电机驱动宽调速范围研究

The parallel hybrid converter (PHC) is a potential alternative to the modular multilevel converter (MMC) for medium-voltage (MV) drive applications due to its remarkable features of lower static energy storage, fewer devices, and zero-voltage switching. Interestingly, for PHC-based variable speed drives, the submodule capacitor voltage ripple (CVR) is not highly affected by the operating speed, un...
