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 3):
The motor drive device according to  claim 2 , further comprising:\n a power calculation unit configured to calculate a driving power requirement as an amount of DC power involved in driving the motor during the allowable power failure time, wherein the boosting ratio control unit controls the boosting ratio so that an amount of DC power stored in the DC link capacitor and available to drive the motor during the allowable power failure time is larger than the driving power requirement.
