Patent ID: 11894766

Abstract:
Disclosed is a three-phase interleaved resonant converter, which includes a three-phase inversion circuit connected to an input voltage and including a first output node, a second output node, and a third output node, a three-phase transformer including three transformers, a three-phase resonant circuit including three resonant capacitors and three resonant inductors, and a three-phase rectifier filter circuit. One ends of the three resonant inductors are respectively connected to the first output node, the second output node and the third output node, and the other ends of the three resonant inductors are respectively connected to a triangular configuration formed by an alternate connection of the three resonant capacitors with primary windings of the three transformers. The three-phase rectifier filter circuit is connected with secondary windings of the three transformers to rectify and filter secondary currents output by the secondary windings of the three transformers respectively, and generate an output voltage accordingly.
