^{Power supply products produced by power supply manufacturers need to pass various certifications, whether at home or abroad. The US Federal Communications Commission and the European Union introduced regulations on commercial digital products in 1990. Regulations require companies to ensure that their products meet stringent magnetization and emission criteria. Products that comply with these regulations are said to be electromagnetically compatible. The electromagnetic compatibility of the power supply has been receiving more and more attention in recent years. Today, Shenzhen power supply manufacturers will take you to understand what is electromagnetic compatibility.}

^{The electromagnetic compatibility (EMC) of a switching power supply means that the switching power supply, power adapter or power transformer does not degrade its performance index due to electromagnetic interference under the specified electromagnetic environment level, and the electromagnetic radiation generated by itself is not greater than the specified limit power. Flat, does not affect the normal operation of other electronic equipment or systems, and achieves the non-interference between the switching power supply and the equipment, the switching power supply and the system, and the purpose of working together reliably.}

^{The definition of electromagnetic compatibility in the national standard "electromagnetic compatibility terminology" is "A device or system can function properly in its electromagnetic environment and does not constitute an unacceptable electromagnetic interference capability to anything in the environment.}

^{The technical fields or service objects involved in the Institute of Electromagnetic Compatibility include almost all electrical equipment. At present, more and more countries have adopted electromagnetic compatibility standards as the basis for evaluation of the performance of switching power supply adapters, chargers, power transformers or electronic products. With the high speed and digitization of electrical and electronic equipment, especially the EU according to the 89/336EEC directive. Since the enforcement of the electromagnetic compatibility standard in January 1996, the world's EMC research on switching power supplies, chargers, transformers and electrical and electronic products has been launched.}

^{Electromagnetic compatibility requires systems that switch power adapters, chargers, power transformers, or electronics to have the ability to withstand certain electromagnetic interference. That is, it should not be subject to interference from other electronic devices or electronic systems in the same electromagnetic environment, resulting in impermissible performance degradation.}
