Abstract
A power conversion device includes a first AC-DC conversion section generating DC voltage applied to a compressor drive section, a first DC-voltage smoothing section smoothing DC voltage, a first noise reduction section having one end connected to an AC power source and the other end connected to the first AC-DC conversion section, a second noise reduction section disposed between the first noise reduction section and the first AC-DC conversion section, an inrush-current inhibition circuit (a first inrush-current inhibition resistor and a rectifier diode) connected in parallel with the second noise reduction section and the first AC-DC conversion section for inhibiting inrush current from flowing to the first DC-voltage smoothing section, a first AC power-source relay opening/closing a power supply path to the inrush-current inhibition circuit, and a second AC power-source relay opening/closing a power supply path to the second noise reduction section.
