摘要 |
A motor drive control apparatus (1) according to the present invention includes: a three-phase rectifier (10) to rectify an AC voltage supplied from a three-phase AC source (6); a booster circuit (20) including a reactor (21), a switching element (22), and a backflow preventing element (23), to boost a DC bus voltage supplied from the three-phase rectifier (10); a smoothing capacitor (30) to smooth an output of the booster circuit (20); and an inverter circuit (40) to convert the DC bus voltage smoothed by the smoothing capacitor (30) into an AC voltage and supplying the AC voltage to a motor. During a starting operation of a boosting operation of the booster circuit (20) or a stopping operation of the boosting operation thereof, a rotation speed of the motor is fixed. |
