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 9):
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 a 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 the positive-side arm of the first leg and the negative-side switching element constituting the negative-side arm of the second leg are turned on and off at the same time and the negative-side switching element constituting the negative-side arm of the first leg and the positive-side switching element constituting the positive-side arm of the second leg are turned on and off at the same time, and to repeat a power transmission period during which each switching element is controlled to turn on and off with a determined switching cycle in the dual-leg resonant mode and a power non-transmitting period during which all switching elements are turned off without being controlled to turn on and off, and thereby controls output power of the inverter by means of a ratio between the power transmission period and the power non-transmission period.
