Abstract:
A full-bridge inverter is configured with a parallel connection of a first leg and a second leg, and controlled in a dual-leg resonant mode in which a positive-side switching element of the first leg and a negative-side switching element of the second leg are turned on/off at the same time and a negative-side switching element of the first leg and a positive-side switching element of the second leg are turned on/off at the same time, and controlled in a single-leg resonant mode in which the positive-side switching element of the first leg and the negative-side switching element of the second leg, and the negative-side switching element of the first leg and the positive-side switching element of the second leg are turned on/off shiftedly in time by a phase shift amount.

Claim (Index 1):
A power conversion device comprising:\n a full-bridge inverter configured with a parallel connection of two legs: a first leg and a second leg, each having two switching elements constituting respective arms connected in series, each arm having a capacitor connected in parallel with the switching element and a diode connected in anti-parallel with the switching element; a transformer, a primary side of the transformer being connected to the full-bridge inverter; a rectifier circuit connected to a secondary side of the transformer; and a controller configured to control the switching elements constituting each arm of the first leg and the second leg, wherein one end of the parallel connected legs is connected to a positive terminal of a DC power source and the other end is connected to a negative terminal of the DC power source, and a point in the series connection between the arms of the first leg and a point in the series connection between the arms of the second leg are connected to the primary side of the transformer, to supply an AC voltage to the primary side of the transformer, and wherein the controller controls the inverter to operate in a dual-leg resonant mode in which a positive-side switching element constituting a positive-side arm of the first leg and a negative-side switching element constituting a negative-side arm of the second leg are turned on and off at the same time, and a negative-side switching element constituting a negative-side arm of the first leg and a positive-side switching element constituting a positive-side arm of the second leg are turned on and off at the same time, or to operate in a single-leg resonant mode in which the positive-side switching element of the first leg and the negative-side switching element of the second leg are turned on and off shiftedly in time by a phase shift amount, and the negative-side switching element of the first leg and the positive-side switching element of the second leg are turned on and off shiftedly in time by the phase shift amount.
