摘　　要：近年来,变频技术大量应用在家电产品中,如空调、冰箱、洗衣机、热水器等。变频技术的应用能给家电带来节约能耗、降低噪音等如多优点,但同时由于其本身的技术特性,变频技术的应用也对整个电力系统或其他电器带来了电磁干扰,造成家电运行不正常的负面影响。本文以变频冰箱为实例,论述了变频技术产生干扰的原因、种类及解决措施。In recent years, the frequency conversion technology is widely used in household appliances, such as air conditioners, refrigerators, washing machines, water heaters, etc. The application of frequency conversion technol- ogy can save energy consumption and reduce noise. But at the same time, because of its own technical characteristics, the application of frequency conversion technology also brings the electromagnetic interference to the whole power system or other electrical appliances, which causes the negative influence of the abnormal operation of the household appliances. In this paper, taking inverter refrigerator as the example, this paper discusses the causes of interference caused by frequency conversion technology, types and solutions.
