Abstract:
1. A power source apparatus comprising: a power factor correction circuit comprising: a first series circuit that consists of a first rectifier element, a first switching element, and a third rectifier element, a second series circuit that consists of a second rectifier element, a second switching element, and a fourth rectifier element, and is connected in parallel to the first series circuit, a smoothing capacitor that is connected in parallel to the first and second series circuits and a load circuit, and a reactor, one end of which is connected to a connecting point between the first rectifier element and the first switching element and the other end of which is connected to a connecting point between the second rectifier element and the second switching element; and a control circuit unit that inputs an alternating current voltage of an AC power source and an output voltage output to the load circuit, and controls a switching operation of at least the first and second switching elements; wherein one end of the AC power source is connected to a connecting point between the first switching element and the third rectifier element and the other end of the AC power source is connected to a connecting point between the second switching element and the fourth rectifier element; wherein the power source apparatus further comprises:
