摘　　要：Synqor电源模块是一种高效率、高可靠的DC-DC变换器模块。文中对其工作原理、设计特点进行了分析和叙述,介绍了电源模块并联的一些使用方法,并给出了应用实例。实验结果表明,该电源模块的拓扑结构与正激拓扑结构相比,具有导电损耗小,电路动态性能好等特性;其并联使用时,满载效率可达86%。The power module of Synqor is a kind of DC-DC converter module having high ethclency and high reliability. The principle and characteristics of it are analyzed and described in this paper. The parallel con- nections for the use of the power supply module are introduced and the representative application examples are given. The experimental results show that the topology of the power supply module has small conduction losses and circuit dynamic performance characteristics compared with the forward topology; when it is used in parallel, the full load efficiency will be up to 86 %.
