This paper proposes a Zero Voltage Switching (ZVS) method for an isolated DC to three-phase AC converter using an indirect matrix converter at the secondary side of the transformer. Phase-shift control is applied to the inverter at the primary side of the transformer, while Pulse Density Modulation (PDM) is employed to the indirect matrix converter at the secondary side. The inverter at the secondary...
This paper presents an isolated type of single-phase matrix converter topology for PHV/EV on-board battery chargers. The proposed converter is comprised of a full bridge inverter, a high frequency transformer and a matrix converter. Due to the lack of DC link bus in matrix converter, in order to suppress the power fluctuation, a power decoupling method which only employs a center-tapped high frequency...
This paper verifies an isolated DC-AC power converter using a single phase to three phase matrix converter in experiment. A matrix converter does not require the large reactors and the large smoothing capacitors in a DC-link part. Furthermore, the proposed control method enables zero voltage switching of the matrix converter by implementing a phase shift control on the primary inverter and a pulse...
