In order to improve the dynamic responses of multimode controlled primary-side regulation flyback converter, a novel digital control method is proposed in this paper. A new DAC sampling method, which can capture the output voltage during dynamic transition, is introduced. Based on it, a dynamic module which can monitor the variation of the output voltage to improve the dynamic performance is proposed. In a 5-V/1-A primary-side regulation flyback converter, the maximum undershoot voltage and… CONTINUE READING
