Abstract:
This power conversion device includes: a rectification circuit; an inverter circuit having a full-bridge configuration, and having a DC capacitor, and first and second legs each of which has two switching elements connected in series to each other; a transformer; and a control circuit for controlling operation of the inverter circuit, wherein the control circuit controls an ON period for the first leg, thereby controlling increase/decrease in current flowing through a first rectification circuit from an AC input, and controls an ON period for the second leg and a phase shift amount between the ON period for the first leg and the ON period for the second leg, thereby controlling voltage of the DC capacitor to be constant. Thus, it becomes possible to achieve high-power-factor control and output power control at the same time by a single stage of full-bridge inverter circuit.

Claim (Index 17):
The power conversion device according to  claim 15 , wherein\n the control circuit uses:\n a first operation mode in which the first switching element and the fourth switching element are turned on; \n a second operation mode in which the first switching element and the third switching element are turned on; \n a third operation mode in which the second switching element and the third switching element are turned on; and \n a fourth operation mode in which the second switching element and the fourth switching element are turned on, and \n the control circuit controls the inverter circuit, using a first operation sub mode in which respective periods of the first to fourth operation modes are controlled in this order, and a second operation sub mode in which the respective periods are controlled in order of the fourth operation mode, the third operation mode, the fourth operation mode, and then the first operation mode.
