摘要： An interleaved LLC half-bridge series resonant converter having an integrated transformer includes a power supply, a magnetic core, a first converter, a second converter and an output load circuit. The magnetic core has first and second outer columns and a center column. The first converter includes a first switch circuit, a first resonant tank, a first transformer, and a first rectifier circuit. The first transformer is coupled to the first resonant tank and includes a first primary winding wound on the first outer column and a first secondary winding wound on the second outer column. The second converter includes a second switch circuit, a second resonant tank, a second transformer and a second rectifier circuit. The second transformer is coupled to the second resonant tank and includes a second primary winding wound on the first outer column and a second secondary winding wound on the second outer column.
