随着高频开关电源技术的不断发展,大功率直流电源系统可以用多台开关电源模块并联的方式实现,于是各电源模块之间均流技术的重要性与日俱增.本文在对开关电源模块并联运行时不均流的原因进行分析,还介绍了现有的开关电源模块并联运行时常用的几种均流的方法,总结了这些方法的优缺点.并指出,随着可编程控制器件在开关电源模块控制系统中广泛的应用,基于可编程控制器的数字均流方法也将以其灵活性、精确性、抗干扰能力强等各方面的优点将取代其他均流方法.

With the developing of the high frequency switch model power supply, high-power supply can be made up by many switch power supply models, so the current-sharing method between each switch power supply model is becoming more and more important, This dissertation introduce some current-sharing methods base on analyzing the reason of current imbalance, summing up the merits and demerits for these method, and point out that the current-sharing method which based on the programmable device will replace the exited method, with the reason of flexibility, accuracy, anti-jamming capability and so on.
