基于三次谐波电压注入的全桥模块化多电平变换器储能需求优化

Full-bridge submodule (FBSM) capacitance of an FBSM-based modular multilevel converter (FB-MMC) can achieve a significant reduction with boosted ac voltages, which makes it a promising candidate in voltage-source-converter-based high-voltage-direct-current scenarios in terms of cost reduction and dc short-circuit fault tolerance. With consideration of third-order harmonic voltage injection (THVI),...
