A resonant converter

Abstract

The present disclosure is related to a resonant converter. The resonant converter includes a primary-side switching circuit, a resonant circuit, a transformer circuit, and a secondary-side switching circuit. The plurality of resonant tanks of the resonant circuit are coupled to the plurality of output nodes of the primary-side switch circuit in a wye connection. Each of a plurality of transformers of the transformer circuit includes a primary winding and a secondary winding. The primary windings are coupled to a plurality of resonant tanks in a delta connection. A plurality of input nodes of the secondary-side switching circuit are coupled to the secondary windings of the transformer circuit in a wye connection. The present disclosure reduces the magnetic flux density through the configuration of the plurality of resonant tanks, thereby reducing the magnetic core loss and having a good current balancing effect.
