摘要
针对多路输出DC/DC变换器存在的输出精度与交叉调整率问题,提出了三种改善措施:变压器堆叠绕法、输出电感耦合与输出比例取样反馈,同时给出了设计实例。针对多路供电系统中设计者需要考虑各路之间的上电顺序,提出了一种有效的上电时序控制方法。
Three methods are adopted to improve the performance of output precision and cross regulation in the multi-output switch mode power supply, including stack wire wound of transformer, output inductance coupling and output proportional sampling. A design sample is given. Designers must consider timing difference during power up in multi-way feed systems. An effective timing control method for power up is realized.
