Power conversion device

A power converter comprising:

• a converter circuit (10) configured to convert alternating current into direct current;
• and
• an inverter circuit (40) connected to the converter circuit (10), and configured to convert the direct current, into which the alternating current has been converted, into alternating current,
• the power converter being configured to supply the alternating current, into which the direct current has been converted by the inverter circuit (40), to a compressor (CM),
• the power converter further including:
• a compensation current output (80) configured to output compensation current (Ic), which compensates for leakage current (Ia) leaking from the compressor (CM), to a current path through which the leakage current (Ia) flows;
• and
• a controller (50) configured to switch between on and off operations of the compensation current output (80) according to a rotational speed of the compressor (CM).
