最小化全桥子模块模块化多电平变换器

In this article, a new modulation scheme is proposed to minimize the device-level current stress in full-bridge submodule based modular multilevel converter (FBSM-MMC), operating under extended modulation. Unlike conventional methods, the proposed approach inserts submodules as a combination of positive and negative voltages. This unique strategy alters device loading patterns, effectively redistr...
