This paper presents a new modulation method for a bidirectional isolated three-phase AC/DC Dual-Active-Bridge (DAB) converter to realize higher efficiency in wide output voltage range. The proposed modulation method realize the bidirectional power flow control with Zero Voltage Switching (ZVS) in al...
