Design of Magnetic Integrated Transformer for LLC Resonant Converter

Abstract:

There are altogether three magnetic components in the resonant tank of LLC resonant converter: the series resonant inductor, the parallel inductor and the transformer. The method to realize the magnetic integrated transformer in LLC resonant converter is presented. The design process is provided, and a magnetic integrated transformer is constructed and the test results correspond well with the design values. A prototype of 1350 W, 100 kHz LLC resonant converter type electric vehicle DC/DC converter equipped with the magnetic integrated transformer is built to verify the performance of the magnetic integrated transformer, and the efficiency at 320 V input, 13.5 V/100 A output is 91.5% at the switching frequency of 100 kHz.
