| Abstract: | Abstract： Through the analysis of establishing flyback converter small signal model, the paper puts forward to a new flyback converter compensating control method, and analyses the feasibility of flyback type switch power used in output feedback based on UC3842. Compared with outperforms conventional control method, this method has quick dynamic response, high stability of closed- loop gain, good voltage ripple, small load regulation rate amt low voltage adjustment rate. |
