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 34):
The power conversion device according to  claim 26 , further comprising a smoothing reactor connected to a DC terminal of the second rectification circuit, wherein\n the control circuit controls the ON period for the first leg on the basis of a voltage value of the DC capacitor, a voltage value of the smoothing capacitor, a current value of the smoothing reactor, a calculated value of a duty cycle for the first switching element, a duty cycle for the second switching element, and a calculated value of the phase shift amount for the second leg.
