Abstract :
In this paper, a modulation method for a single-stage three-phase AC-DC converter with only two active switches on the AC-side is proposed. The Dual Active Bridge (DAB) based modulation provides the advantages of Zero Current Switching (ZCS) for the primary side switches, linear power relationship for easy control implementation and unity power factor with open-loop control. Some other features of this topology are galvanic isolation and bi-directional power flow capability. This converter is analysed and the conclusions of the analysis and simulation concur.
