| Abstract: | An improved Buck ZCS - PWM converter was presented in this paper, in which the functions were simulated. The converter worked at a constant frequency with simple DC transmission ratio and excellent load characteristics. Zero current could be implemented by the main switch and the assistant switch. It proved to be more reliable than the traditional ZCS - PWM converters in both academic analysis and simulation results. |
