摘要
微波炉存在EMI问题,国际上对家用微波炉规定了严格的EMI标准。微波炉中电磁干扰的主要源头之一是磁控管,如果微波炉和磁控管的设计协调,微波炉整机的EMI会得到很好的抑制。文章就微波炉和磁控管的相关设计与EMI测试关系进行了讨论,在成本和测试效果之间找到了平衡点。
Microwave oven is recognized as the household electric product which could emit EMI. Standards on national and International Level prescribe strict EMI limits for household microwave oven. The one of EMI source in microwave oven is magnetron. If the design of microwave oven and magnetron is appropriate, we can get good results about EMI from microwave oven. This article discussed about the relation of the interrelated design of magnetron and microwave oven and EMI test, and tries to find a balance point between cost and test.
