Dc/Dc Resonant Converter with a One-seith Synchronous Regulator

摘要

The paper presents a resonant dc/dc converter with a one-switch synchronous regulator and a Class E amplifier.The circuit diagram,its principle of operation and a theoretical analysis of a one-switch synchronous regulator and experimental results for resonant dc/dc converter are given.The presented one-switch synchronous regulator [1] is a modification of a two-switch synchronous regulator [2],[3].Due to resonant technque of shaping current and voltage waveforms in semiconductor switches in these power-supply systems swithcing losses have been reduced.This advantage makes possible to operate the converter at a high and constant frequency with good efficiency,which enables it to achieve a high degree of miniaturisation as well as a low level of emitted electromagnetic interferences.The proposed circuit can find applications in power-supply systems in telecommunications,aircraft and computers.
