Abstract
A primary-side controlled universal-line flyback converter is widely used for its low-cost and low standby power advantages; however, conventional overpower protection schemes with primary-side control suffer from inaccurate protection. In this paper, a novel scheme will be reported to achieve a very significant improvement in overpower accuracy. This scheme was implemented successfully in an integrated circuit without adding any extra pin compared to conventional schemes. Experimental and simulation results verified the proposed strategy.
