The steady principle of active clamp flyback converters is investigated. In order to predict effects of the active clamp circuit on the small signal properties of active clamp flyback converters,the converter′s average model and small signal model by using the state-space averaging approach are presented. Schematic test results and Matlab simulation of small signal properties are given. The designed and developmented current controlled active clamp flyback converter has the merits such as high density, high conversion efficiency, high realiability, and strong ability of overload and short-circuit.
