  • In this paper, a new method of SVPWM implementation for 3-Phase 3-Leg 3-Level AC/DC converter known as the Vienna converter is proposed. Also the performances of PI and PR controller used in AC input current controller are compared. To verify the proposed method, PSIM, a power electronics simulation program, is utilized. The performances of the proposed new method and the two existing methods are compared through simulation and experiment. Also PI and PR controller in AC input current controller are compared through 10[kW] Vienna converter system.
