This paper introduces a more practical method for linearly controlling leakage inductance. Various integration methods are meticulously compared to identify the most effective approach. Furthermore, we present a detailed winding structure designed to minimize winding loss, thereby enhancing overall efficiency. To validate these concepts, a 22-kW three-phase CLLC resonant converter prototype was developed. The prototype's topology is illustrated in Fig. 1, and its specifications are detailed in Table I.
