Inverter device

Abstract

To suppress torque fluctuations that occur when switching control systems. The inverter, which performs a power conversion operation for converting DC power into AC power, includes an arithmetic control device INV200 which is provided with a voltage command signal generation unit 620, a synthesis processing unit 670, and a carrier wave comparison unit 680. The voltage command signal generation unit 620 has a plurality of control systems, and outputs the first voltage command signal generated based on the first control system among the plurality of control systems, and the second voltage command signal generated based on the second control system different from the first control system among the plurality of control systems. The synthesis processing unit 670 generates a synthesized voltage command signal obtained by synthesizing the first voltage command signal and the second voltage command signal at a predetermined ratio. The carrier wave comparison unit 680 generates a PWM signal which is a gate drive signal for controlling the power conversion operation based on the synthesized voltage command signal.
