고집적 스위칭 전원을 위한 LLCT 설계 및 Half-Bridge 직렬공진 컨버터

LLCT design and half-bridge series resonant converter for high density switching power supply

High density power supply technology has been researched over the last few years. In this paper, integrated LLCT(Inductor-Inductor-Capacitor-Transformer) structure is described for use in the half-bridge series resonant converter. The structure is analysed by means of FEMM(Finite Element Method Magnetics) and the experimental results of an U structure for a 300W converter we presented.
