| Abstract: | A multiple-output switching single-ended flyback power supply based on current mode pulse-width-modulation(PWM) controller is designed in this paper.With weighted output-voltage control and winding arrangement of the transformer,cross regulation of the designed multiple-output power supply can be effectively improved.Experiment results show that voltage regulation and cross regulation of 15V output are 1.6% and 4.86% respectively.Furthermore,the designed circuit,characterized by simple implementation,high efficiency and reliability,has a great applied importance. |
