Beschreibung
Zusammenfassung:	A power conversion apparatus that converts an input alternating current power supplied from an alternating current power supply into an output alternating current power having a predetermined voltage and frequency, includes an inverter circuit configured to supply the output alternating current power to a motor, and a compensation unit configured to compensate for a harmonic of an input power of the motor, and the compensation unit detects a harmonic component generated in synchronism with a speed of the motor in the input power, and varies a phase of an alternating current voltage output from the inverter circuit at the same frequency as the harmonic component, so as to reduce the harmonic component.
