In this paper, the AC small signal model of single-ended flyback power supply in CCM mode using average switching elements model approach is introduced. Analysis and establish power supply model based on TOPSwitch chip, and design controller with frequency domain method. The results of MATLAB simulation certify that compensation network is reasonable. 32W prototype is developed, output ripple is less than 5% and voltage regulation rate is about 2%.
