To improve the constant output voltage accuracy of primary-side controlled flyback converter, this study described a digital control scheme based on accurate sampling and cable voltage drop compensation. The voltage drops of output diode and the cable were analysed first, they were two most important factors that influence the accuracy of output voltage. Then, an accurate sampling method that can...
This study described a novel digital regulation scheme for multimode primary-side controlled flyback converter. This approach ensured good energy continuity at the modes transition points of the converter. Compared with the normal control methods, the proposed digital regulation scheme could achieve smooth modes transition and suppress the large output voltage ripple when the converter works at the...
