Summary:The utility model relates to the technical field of motor driving power supplies, and discloses an AC asynchronous motor driving device. The inverter mainly comprises a boosting unit (100), a controlunit (101) and an inversion unit (102), the inversion unit (102) comprises an IGBT bridge arm. The control unit (101) sends a trigger signal to the boost unit (100). Wherein the boosting unit (100) isconducted to work, low-voltage direct-current voltage is converted into high-voltage direct-current voltage to be output to the inversion unit (102), the control unit (101) sends a trigger signal tothe IGBT bridge arm, and the IGBT bridge arm is alternately conducted to work to convert the high-voltage direct-current voltage into pulsating alternating-current voltage. And the control unit (101)is also used for acquiring, comparing and monitoring the information of the alternating-current voltage and controlling the alternating-current voltage output by the IGBT bridge arm. The alternating-current asynchronous motor dr
