A resonant converter and an integrated magnetic core module

Abstract

The present disclosure is related to a resonant converter. 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 of the transformer circuit includes a primary winding and a secondary winding. The output ends of the primary windings are coupled to each other in a wye 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. The input nodes are coupled to equal secondary windings of the transformer circuit in a wye connection. The present disclosure reduces the core loss through the configuration of a plurality of resonant tanks and the transformer, and has a good current balancing effect, thereby achieving the effect of reducing the overall loss of the power circuit.
