| Abstract: | Concerned with the problems of voltage overshoot and oscillation of switching transistor when turning-off switch in the traditional push-pull circuit, an improved scheme of active clamping circuit used for Boost converter was proposed. First, the operating principle of the improved circuit was analyzed, and then some relative formulas given. By using the improved circuit the zero voltage switching （ZVS） can be implemented, reducing the cyclic energy loss via the full-bridge rectifier with the secondary clamping. Finally, the results of circuit simulation and experiment verify the correctness of the related theoretical analysis. |
