【Abstract】 The flyback converter with a winding clamp circuit is analy zed. The operation principle and the design criteria of the clamp circuit ar e given. Experimental results verified the correctness of the theoretical analys i s. The energy stored in the leakage inductance can be feed back to the output w i th the clamp circuit. Therefore, the efficiency of the converter is improved. T h e cross regulation of the multiple-output flyback can be also improved with thi s circuit.更多还原
