| Abstract: | The analysis and design of 48 kW high frequency switching power supply are presented. The present state of switching power supply is explained. The operating principle of full bridge phase - shifted converter and realization of soft switching techniques are analysed. Soft switching can reduce switching loss and increase circuit＇s efficiency. Integer designing of power supply system and selection of main device parameters are also proposed. The experiment results demonstrate the power supply device satisfies design requirements completely. It has been applied in electric plating production line success -fully. |
