| Abstract: | An inverter power supply of phase-shifted PWM(PS-PWM)control based on DSP is introduced.The topology of the main circuit based on IGBT is presented.The control principle is analysed and the control circuit based on DSP is designed be-sides the presentation of program flow chart.The digital control and DPLL of the system was achived based on the DSP TMS320F2812.The demand on real time character and flexibility was implemented.The simulative and experimental results de-montrate that the soft-switching of the inverter is accomplished in great scopes of power modulation and frequency conversion. |
