| Abstract: | The advantages and drawbacks of three kinds of reset circuits for the active clamp forward converter are com-pared and analyzed.The effects of magnetizing current in the active clamp forward converter are analyzed and the small signal model of peak current controlled active clamp forward converter is accomplished through the small signal model of three basic converters.Finally,the simulative and experimental results are shown to explain the effects of active clamp cir-cuit on the small signal properties of ... |
