This paper proposes a successive injection modulation (SIM) method for a direct three-phase to single-phase AC/AC converter of a contactless electric vehicle (EV) charger. The converter has a fewer bi-directional switches than a matrix converter without a neutral line connection. It operates using injection and free-wheeling oscillation commutations based on a zero-current switching mechanism. Analytical calculations were derived using a steady-state analysis. Simulation results were obtained to validate the calculations. The proposed modulation increases output power three times compared to a non-successive one with the same circuit setup.
