Abstract :
In this study, the principle of a phase-shifted full-bridge zero voltage switching ZVS DC / DC converter is analyzed. It focuses on soft-switching implementation, selection of rectifier bridge,parasitic oscillation suppression, voltage-type single-loop control and other issues. The implementation scheme of full digital control based on TMS320LF2407 is given. Then the system´s hardware and software is designed. Finally the experiments is carried out, which experimental waveform is given.
