==Original Abstract Submitted==

A DC power supply device includes a rectification circuit, a reactor, a first capacitor and a second capacitor, a first switching element to set the first capacitor in a charging state when the first switching element is in an off state and to set the first capacitor in a non-charging state when the first switching element is in an on state, a second switching element to set the second capacitor in the charging state when the second switching element is in the off state and to set the second capacitor in the non-charging state when the second switching element is in the on state, and a controller. The controller has a full-wave rectification mode as an operation mode in which one of the first and second switching elements is maintained in the off state and the other one of the first and second switching elements undergoes PWM control.
