Title:
NON-ISOLATED FULL-BRIDGE CASCADE CONVERTER CIRCUIT AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/027360
Kind Code:
A1
Abstract:
Provided in the present application is a non-isolated full-bridge cascade converter circuit. The aims of reducing the number of turns of a transformer and also reducing an effective value of an electric current of a transformer winding and a rectifier switch device are achieved by means of cascading a full-bridge converter and an output rectifier circuit. Since the number of turns is reduced, the number of PCB layers in a power supply solution is greatly reduced, thereby effectively controlling the cost and shortening the development period; moreover, the efficiency of the converter is greatly improved since the effective value of the electric current flowing through the transformer winding and the rectifier switch device is greatly reduced.
