Abstract
Provided is a power conversion device which comprises a main circuit board, a first board, and a second board and which has a reduced size. The main circuit board has a rectifier circuit and an inverter circuit which are disposed in a high-power section, the rectifier circuit rectifying AC voltage and The second board is provided with a The first board is connected to the main circuit board and to the second board, and is provided with: a first circuit disposed in a low-power section. The second board is provided with a second circuit disposed in a low-power section. section from each other in a reinforced manner; an insulating transformer disposed in the reinforced insulation region and constituting a constituent component of a power supply circuit for receiving the DC voltage and supplying power to the first circuit and to the second circuit; and an insulating element disposed in the reinforced insulation region and allowing a signal to be exchanged between the first circuit and the second circuit.
