Abstract: The flying-capacitor modular multilevel converter (FC-MMC) overcomes the low/zero-speed operation issues of conventional MMC-based drive. The FC-MMC injects no common-mode voltage (CMV) to the drive system. However, the pulse width modulator (PWM) introduces switching ripples,… read more here.
