Electromagnetic Compatibility Test

Product introduction： Summary of test contentElectromagnetic Compatibility EMC (Electromagnetic Compatibility) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment.Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; on the other hand, it means that the equipment has a certain amount of electromagnetic interference in the environment. degree of immunity, ie electromagnetic susceptibility.The International Electrotechnical Commission standard IEC defines electromagnetic compatibility as: a system or equipment can work normally in the electromagnetic environment where it is located without causing interference to other systems and equipment.Why do we do EMC testing?Various operating power equipments are related to each other and affect each other in three ways: electromagnetic conduction, electromagnetic induction and electromagnetic radiation.

Summary of test content

Electromagnetic Compatibility EMC (Electromagnetic Compatibility) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment.

电磁兼容测试

Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; on the other hand, it means that the equipment has a certain amount of electromagnetic interference in the environment. degree of immunity, ie electromagnetic susceptibility.

The International Electrotechnical Commission standard IEC defines electromagnetic compatibility as: a system or equipment can work normally in the electromagnetic environment where it is located without causing interference to other systems and equipment.

Why do we do EMC testing?

Various operating power equipments are related to each other and affect each other in three ways: electromagnetic conduction, electromagnetic induction and electromagnetic radiation. Under certain conditions, it will cause interference, influence and harm to the operating equipment and personnel. The electromagnetic compatibility (EMC) discipline that emerged in the 1980s aims to study and solve this problem. The most reasonable principle of technology and economy, make clear regulations on the level of interference generated, anti-interference level and suppression measures, so that the equipment in the same electromagnetic environment is compatible, and at the same time, it does not introduce into any entity in the environment that cannot be allowed. electromagnetic disturbances.

EMC includes EMI (interference) and EMS (susceptibility), that is, electromagnetic interference and electromagnetic anti-interference. EMI (Electromagnetic Interference) describes the degree of electromagnetic radiation interference of a product to other products, whether it will affect its surrounding environment or the normal operation of other electronic or electrical products in the same electrical environment; EMS (Electromagnetic Immunity) describes an electronic or Whether the electrical product will be interfered by its surrounding environment or other electronic or electrical products in the same electrical environment and affect its normal work.

If the product does not pass the EMC test, the produced product will have many of the above problems that cannot be solved, so it must pass the test of various EMC standards to achieve the integrity of the product performance.
