Abstract :
This paper addresses the design of isolation transformers that integrate all required inductances into one magnetic structure for resonant converters. A design method is presented for components using a power ferrite core, litz-wire windings and an air leakage path. The design method is developed by considering the Q of the leakage inductance to develop a simple and efficient design.
