1. A power conversion device comprising:
a transformer having a primary winding and a secondary winding;
an inverter circuit to provide power supply to the primary winding;
a rectifier circuit to rectify alternating voltage generated in the secondary winding with multiple rectifier elements;
a smoothing reactor whose first end is connected to a first output terminal of the rectifier circuit, to smooth the voltage rectified by the rectifier circuit;
a first main circuit line which connects a second end of the smoothing reactor and a positive output terminal of an output end;
a second main circuit line which connects a second output terminal of the rectifier circuit and a negative output terminal of the output end; and
a smoothing capacitor connected between the first main circuit line and the second main circuit line,
wherein a first mounting surface of the first main circuit line and a second mounting surface of the second main circuit line are provided on an identical plane, the smoothing capacitor being mounted on the first mounting surface and the second mounting surface, and
at least one rectifier element, out of the multiple rectifier elements, is connected to the second mounting surface via the second output terminal.
