Abstract

See full text

A refrigeration device includes a high-voltage electrical parts group having reactors and cooled elements, a low-voltage electrical parts group, a printed wiring board with the electrical parts groups mounted, and a refrigerant jacket that uses refrigerant flowing through the refrigerant circuit to cool the cooled elements. The high-voltage electrical parts group form an interleaved power supply circuit. The cooled elements are placed in an order conforming to a power supply path of the power supply circuit. The power supply circuit has a rectifier circuit, a power factor improvement circuit, smoothing capacitors, and an inverter circuit. The power factor improvement circuit has the reactors connected to each other in parallel and diodes and switching elements serving as the cooled elements connected to each of the reactors. The reactors are placed on an opposite side of the smoothing capacitors, with the diodes and the switching elements sandwiched in between.
