Current Stress Reduction for Flying-Capacitor Modular Multilevel Converter
Abstract
Flying-capacitor modular multilevel converter (FC-MMC) overcomes the zero/low-fundamental-frequency operation issues of conventional MMC without injecting common-mode voltage. However, the FC-MMC suffers from high current stress due to the large amplitude of inner high-frequency current. The square-wave design for the inner high-frequency components could effectively reduce the current stress, but the per-phase LC circuit (formed by arm …
