Abstract

A power supply device is equipped with a first boost converter including a first reactor of a first inductance and with a second boost converter including a second reactor of a second inductance that is a different value from the first inductance, as converters that are connected in parallel to each other and configured to transmit electric power with conversion of voltage between a power storage device side and an electric load side. The first boost converter and the second boost converter have different resonance frequencies. This configuration suppresses the occurrence of resonance with a load variable frequency of the electric load.
