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 focuses. 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.
