Abstract:
A motor drive device includes a PWM converter configured to convert AC power supplied from an AC power supply into DC power and supply it to a DC link, a DC link capacitor which is provided in the DC link and may store the DC power, an inverter configured to convert the DC power in the DC link into AC power for motor driving and output it, and a boosting ratio control unit configured to control the boosting ratio as the ratio of the value of the DC voltage output from the PWM converter to the peak value of the AC voltage input from the AC power supply, to allow a motor to be driven using AC power output by converting the DC power stored in the DC link capacitor by the inverter during shut-off of supply of the DC power from the PWM converter to the DC link.

Claim (Index 2):
The motor drive device according to  claim 1 , wherein the boosting ratio control unit controls the boosting ratio, based on an allowable power failure time set in advance as a period of time in which the motor is allowed to be driven using the AC power output from the inverter during shut-off of supply of the DC power from the PWM converter to the DC link due to power failure in the AC power supply.
