Design and Optimization of the MMC-Based Power Electronic Transformer Considering Ripple Power Transfer

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 RP...
