To suppress zero-sequence circulating current in parallel operating inverters with common DC power supply, this paper proposes a new strategy based on Dual-carrier SVPWM and proportional resonant (PR) control, which use two opposite active vectors instead of zero vectors to suppress the higher frequ...
