并联开关电源的均流技术

近来开关电源（ＳＭＰＳ）发展趋向于并联运行，以便通过Ｎ＋１冗余获得故障容错及冗余功率，并且建立模块式分布电源系统，以增大总负载电流。在并联开关电源设计中要采用特殊的均流技术，使并联联接的开关电源间负载电流能均匀分配。本文讨论了并联开关电源中常用的若干均流技术，研究其特性和明显的特点及其它有关问题。

LOAD SHARING TECHNIQUES FOR PARALLEL SWITCHING MODE POWER SUPPLIES

The switching mode power supply(SMPS )technology recently is evolving towardparallel operation to obtain fault-tolerant, redundant power by N+1 redundancy and tocreate a modular power distribution system to increase the total load current. Special load sharing techniques are employed in a parallel SMPS design to equally dis-tribute the load current among the parallel SMPS.This paper will examine several load sharing techniques used in parallel SMPS with anattempt to investigate their application,highlighting features and others.
