| Abstract: | The interleaved flyback converter of SPWM control, makes good use of the advantages of the converter Combined with the fast response and high stability characteristics of SPWM. It has the characteristics of simple topology, small ripple of the output, high stability, small voltage spike of the power switch and so on. It introduced the principle of the complementary output to realize the de half- sinusoid transform of the output of the interleaved flybaek converter of SPWM control, and the theoretical analysis of the principle and method for generating SPWM by DSP. The results of the experiment verified the feasibility of the design, it enhances the overall performance of the circuit and it wouldn＇t increase the burden of the design of hardware circuit. |
