<p>This motor inverter device is equipped with: a full-wave rectification circuit (2) that utilizes a single-phase alternating-current source for input; an inverter (4) for converting direct-current power into alternating-current power; a control unit for driving the inverter by means of PWM; a smoothing unit (7) that has a resonance frequency which is set higher than the frequency of the single-phase alternating-current source by forty times or more, and is composed of a reactor and a capacitor; and a motor (3) that is a permanent magnet motor which includes a reluctance torque in an output torque. A timing advance adjustment unit (80), which adjusts the phase of a PWM control signal output from the control unit, is regulated such that a regenerative current from the motor takes a value within a predetermined range as a result of the timing advance adjustment.</p> |
