With the development of electronic appliance technology, the popularity and electronization of household appliances are increasing, and radio and television, post and telecommunications and computer networks are becoming more developed, leading to more complex and deteriorative electro-magnetic environment. Therefore, governments and manufacturers of various countries pay more attention to the electro-magnetic compatibility (EMC electro-magnetic interference EMI and electro-magnetic anti-EMS) of electronic appliance products.
