Title:
ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/186991
Kind Code:
A1
Abstract:
A switching circuit switches on and off a current to be supplied to a resonance circuit wherein a first winding wire of a transformer, a capacitive component, and an inductor are connected in series. Electricity induced in a second winding wire of the transformer is rectified by a rectification circuit. A switch is connected in parallel to the capacitive component. A control unit controls the switching circuit and the switch. The control unit selects between a first operation whereby the switch is opened, and the operating frequency of the switching circuit is controlled and a second operation whereby the switch is closed, and the period for conducting the electricity from the switching circuit to the first winding wire of the transformer is controlled.
