Abstract :
The aim of this paper is to analyze the power factor correction capability of isolated current-source resonant converter topologies with two energy storage elements, which takes advantage of the leakage inductance of the HF transformer. These converter topologies are studied and modeled. Computer simulation results are also given. Thanks to its interesting characteristics, a converter topology is chosen and a converter prototype is built in order to validate theoretical study. Using this converter topology, a very good power factor is achieved
