| Abstract: | An welding power supply of soft-switching based on DSP is introduced.The topology of the main circuit based on zero-voltage zero-current switching(ZVZCS)PWM DC/DC convertor is presented.The control principle is analysed,the control circuit based on DSP is designed besides,and the program flow chart is presented.Using of TMS320F2812 DSP can optimize the control of the waveform for the power supply,make the system more compact and also meet the demand on real-time character and flexibility. |
