摘要: When instructed to switch control modes between overmodulation PWM and sinusoidal wave control, device corrects the amplitude of a voltage command signal based on state power conversion operation performed by an inverter, so as suppress change in influence dead time over applied alternating-current motor upon switching modes. The inverter includes at least one present value carrier frequency mode currently employed, estimated be obtained when modes, length time, factor exchanged motor, driving motor.
