| Abstract: | Designed a kind of high frequency switch power supply module with digital-based soft-switching technology based on DSP chip TMS320F2812 for DC power systems.The full bridge zero-voltage zero-current(ZVZCS) shifting phase transformation circuit with diodes series in its lagging leg is adopted.It can achieve zero-voltage switching(ZVS) for leading leg and zero current switching(ZCS) for lagging leg in the wide rang of load;this paper analyzed the converter’s principle of operation,and was verified by experimental prototype. |
