| description | To provide an inverter controller which can improve torque responsiveness of a three-phase AC rotary electric machine in accordance with switching from PWM control to rectangular wave control.SOLUTION: An inverter controller comprises: a PWM control unit which performs PWM control of a switching element of an inverter circuit which drives a motor by outputting a PWM control signal S1; a rectangular wave control unit which performs rectangular wave control of the switching element by outputting a rectangular wave signal S2; a control switching unit 50 which switches the PWM control and the rectangular wave control by switching the PWM control signal S1 and the rectangular wave signal S2 to be output; and an induced voltage calculation unit 52a which calculates induced voltage of the motor on the basis of a current value of each phase of the motor and rotational velocity ω of the motor. The control switching unit 50 switches the signal to the rectangular wave signal S2 to be output when the induced voltage exceeds a threshold in a state of outputting the PWM control signal S1.SELECTED DRAWING: Figure 2
