The paper presents a resonsnt 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 persented one-switch synchronous regulator [1] is a modification of a two-switch synchronous regulator [2], [3]. Due to resonant technique of shaping current and voltage waveforms in semiconductor switches in these power-supply systems switching 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.
