摘要
阐述了一种基于电流型脉宽调制控制器的多路输出反激变换器的设计。采用输出电压加权反馈和变压器绕组设计技术,实现了较高的多路输出电压的交叉调整率。实验结果表明,15V输出的调整率为1.6%,交叉调整率为4.86%。该电路实现简单,效率高,可靠性高,在实际应用中具有重要价值。
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.
