A resonant converter and an integrated magnetic core module

Abstract

A resonant converter is disclosed. The resonant converter includes an input circuit, a primary-side switching circuit, a resonant circuit, a transformer circuit, a secondary-side switching circuit, and an output circuit. Each of the plurality of transformers in the transformer circuit includes a primary winding and a secondary winding. The primary windings are coupled to each other in a star connection, and the secondary windings are coupled to each other in a delta connection. The secondary-side switching circuit is coupled to the transformer circuit and includes a plurality of input nodes. These input nodes are coupled to the secondary windings of the transformer circuit in a star connection. This application reduces core losses and achieves good current balance through the configuration of a plurality of resonant slots and transformers, thereby reducing the overall power supply circuit losses.
