摘　　要：本文介绍了国外用电器待机功率损耗概况及其标准限制,分析了开关电源待机损耗的构成和目前常用的降低待机损耗方法。以大功率笔记本电脑适配器为例,提出并研究了一种并联式电路拓扑结构。试验与测量结果表明,该电路拓扑具有低待机损耗、高效率、快速负载动态响应等优点。In this paper, at first the situation and limitation standards of standby power loss in world wide are introduced. The composing of standby power of switch mode power supply （SMPS） and normal methods for reducing it are analyzed and presented. For example, with high power adaptor for notebook computer, a paralleled type of circuit topology is presented and studied. The that the topology has the advantages of low fast load dynamic response. experiment and measurement results show standby power loss, high efficiency andfast load dynamic response.
