摘要
医用电气设备中的电源,由于其高功率密度、高电流/电压变化率、线路相对集中等因素导致其电磁干扰问题特别严重和复杂,从而不同性质电源的电磁兼容(EMC)表现是目前研究的热点问题之一。本文分析了医疗设备电源的电磁干扰产生机理及传播方式,并对代表性设备进行了EMC标准测试,对其结果进行了分析。
Because of the high power density, high current/voltage rate and the intensive line layout, the power supply unit can lead to serious problems of electromagnetic interference （EMC） for medical equipment. Therefore, the electromagnetic compatibility problem of power supply units for medical equipment is one of the hot research fbcuses. This paper analyzes the mechanism and transmission method of electromagnetic interference of power supply units for medical equipment. Meanwhile, several typical power supply units are tested and the results are analyzed.
