Power Conversion System

Abstract: This power conversion system includes a transformer, N first inverters, N second inverters, and a control unit. The transformer has 2N-system primary windings for three-phase alternating current and a 1-system secondary winding for three-phase alternating current. The control unit controls each of the inverters by PWM control. A first primary winding corresponding to one of the N first inverters and a second primary winding corresponding to one of the N second inverters are determined on the basis of the magnitude of respective percent impedances from the respective primary windings to the secondary winding. A first carrier phase in PWM control with respect to the first inverter and a second carrier phase in PWM control with respect to the second inverter are inverted. Said N is a natural number of 2 or more.
