摘　　要：多路输出电源的负载交叉调节性能一直没有得到较好的解决,给不对称性要求较高的负载应用带来困难。根据闭环控制原理,提出了一种双环路稳定,利用同一时钟脉冲同步的方法,解决了多路输出电源交叉调节互扰大的问题,大大改善了负载交叉调节性能。The load cross regulation of multiple output power supply has not been properly achieved, which results in some problems for the application of highly - required asymmetry load. According to closed loop controlling theory, a double loop stable and synchronous impulse controlling method is put forward, the mutual interference problem of multiple power supply is solved and the load cross regulation capability is improved.
