摘要：A compressor driving device includes: a controller (23) that PWM drives acompressor; an inverter circuit unit (4) that supplies power to an electric motor includedin the compressor; a drive circuit (5) that drives the inverter circuit unit (4) according to acontrol signal; a voltage detector (9) that detects a voltage that is output to the electricmotor; and a current detector (10) that detects a current that is output to the electricmotor. When a product of a detection value of the voltage detector (9) and a detectionvalue of the current detector (10) is greater than a predetermined comparison value, aduty ratio of the control signal is reduced to cause the input power supplied to theelectric motor by the inverter circuit unit (4) to have a predetermined input power levelor less.
