考虑纹波功率传输的基于MMC的电力电子变压器设计与优化

The modular multilevel converter (MMC)-based power electronic transformer (PET) offers the advantage of enabling ripple power transfer (RPT) through inherent dual active bridges (DABs), thereby reducing the required submodule capacitance and enhancing power density. However, the implementation of RPT leads to increased loss and volume of DABs, posing challenges to the operation mode selection and ...
