Title:
ELECTRIC ENERGY CONVERSION DEVICE USING PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2023/003299
Kind Code:
A1
Abstract:
An electric energy conversion device to which a first direct current power obtained by half-wave rectifying a first alternating current power is applied, according to one aspect, comprises: an electromagnetic circuit unit which includes a first solenoid having a first output-side winding and a second solenoid having a first input-side winding and a second output-side winding, and in which iron cores included in the respective solenoids are connected to form a closed circuit of an electromagnetic flux; and a first permanent magnet which generates a first permanent magnetic flux, shares the iron cores of the electromagnetic circuit unit as a movement path of the first permanent magnetic flux, and forms a closed circuit of the first permanent magnetic flux with the electromagnetic circuit unit, wherein the electromagnetic circuit unit generates an induced current in the first and second output-side windings by means of the electromagnetic flux generated and controlled by the application of the first direct current power to the first input-side winding and the first permanent magnetic flux of which the flow is changed by the electromagnetic flux.
