Study On Electromagnetic Compatibility Commonness Problems Of Home Appliances

Electromagnetic Compatibility (EMC) is a cross-disciplinary science based on electromagnetism and drawing upon areas such as information science, electrical engineering, electronics, communications, materials and structures, etc. It is also an applied technology, which is used to study, under the conditions of limited space, limited time and limited frequency resources the compatibility of electrical and electronic devices and systems within the common electromagnetic environment without a degradation of performance. The international society has been paying quite a lot of attention to the Electromagnetic Compatibility (EMC) and EMC have been regulated under the legal requirements and included in the environment protection framework in the industrialized countries and regions, and forming Technical Barriers to Trade.With the increasing number of electromechanical products exporting to many other countries in China, home appliances are the most importance exports of China, Electromagnetic Compatibility (EMC) becoming one of the chief technology guideline of international trade. Many home appliances manufacturers press for helping them solve EMC problems. In this regard, studying on Electromagnetic Compatibility Commonness Problems of Typical Home Appliances and building an expert system which guides users to study on Electromagnetic Compatibility (EMC) and improve the quality of electrical and electronic products and surpass the world's advance levels. It creates favorable conditions for exports of home appliances.In addition, this paper brings forward some common technological problems of EMC about typical home appliances according to EMC test of a frequency conversion air-condition, and gives some countermeasures to anti-interfere about typical home appliances. Study on EMC problems by expert system and have built a Typical Home Appliances that have microprocessor expert system...
