摘要
介绍了正激式DC/DC多路输出电源拓扑,简单介绍了两种精确调节技术:利用磁放大器进行后级调节和次级同步调节技术(SSPR)实现精确输出,并比较了其各自的优缺点。最后以一个设计示例,采用次级同步调节技术,运用AP法讨论了正激式多路输出变压器、耦合电感器的优化设计,以提高多路输出变换器的效率,改善负载调整率、交叉调整率等问题。实验结果表明,采用次级同步调节技术方案有效地提高了多路输出变换器的效率,改善了负载调整率、交叉调整率。
An introduction for forward topology multiple output DC/DC converter is made. A brief introduction was made to the two secondary side control technique, using magnetic amplifier and secondary side PWM regulator. And the differences between the two methods are compared. A simple using the secondary side PWM regulator technique is given to discuss the optimimum design of the converter and coupling inductor, in order to improve the multiple output converter＇s efficiency, cross regulation and load regulation. The result indicated that using the secondary side PWM regulator technique can cnectively improve the efficiency, cross regulation and load regulation.
