Abstract

A power source apparatus includes: a first series circuit that has a first rectifier element, a first switching element, and a third rectifier element; a second series circuit that has a second rectifier element, a second switching element, and a fourth rectifier element; a reactor connected between a connecting point of the first rectifier element and the first switching element and a connecting point of the second rectifier element and the second switching element; and a current detection unit having a first resistor element. The first and second switching elements are controllable based on a first zero current detection signal in accordance with a first current detected in the current detection unit, and a desired direct current voltage is fed to a load circuit.
