摘要: The invention discloses an inverter with a three-phase-transition structure and control method thereof. comprises four bridge arms bidirectional thyristors, wherein output node of first arm is connected positive end A-phase winding; second negative the third C-phase mode fourth B-phase windingis to through thyristor, winding thyristor; or also connect thyristor. Through structure, power loss motor driver reduced when three-phase alternating current in high-torque operation condition; utilizationrate direct-current voltage increased under high-speed range expanded.
