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 27):
The power conversion device according to  claim 18 , wherein\n the control circuit controls the first switching element and the second switching element so that their ON and OFF states are inverted relative to each other, and in an initial state in which the phase shift amount is zero, the control circuit controls a gate pulse width and a phase for the third switching element to be equal to those for the first switching element, and controls a gate pulse width and a phase for the fourth switching element to be equal to those for the second switching element.
