Abstract

In order to meet the needs of switch power supply with high-power density, low-profile and high-efficiency posed by large scale integration (LSI), this paper presents a novel three-level soft switching DC/DC resonant converter with integrated magnetic technology to reduce its losses, volume and weight, to improve its filter effect and increase its power density. In this paper, equivalent circuit of integrated magnetic components is derived and its working modes are discussed. Thin-film technology is used to design integrated magnetic components, then its design results are given.. At last, its simulation results proved the validity of this design
