Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment in accordance with requirements without causing unbearable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it refers to the requirement that the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; On the other hand, it refers to the device having a certain degree of immunity to electromagnetic interference present in the environment, namely electromagnetic sensitivity. The definition of electromagnetic compatibility in the International Electrotechnical Commission (IEC) standard is that a system or equipment can operate normally in the electromagnetic environment it is in, without causing interference to other systems and equipment. EMC includes two parts: EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference refers to the electromagnetic noise generated by the machine itself during the process of performing its intended functions, which is detrimental to other systems; EMS refers to the ability of a machine to perform its intended functions without being affected by the surrounding electromagnetic environment. Electromagnetic Compatibility refers to the normal working ability of various electrical or electronic devices in a complex electromagnetic environment in a common space, meeting design requirements with specified safety factors. Also known as electromagnetic compatibility. Its meaning includes: ① mutual consideration between electronic systems or devices in electromagnetic environments; ② Electronic systems or devices can operate normally according to design requirements in the electromagnetic environment of nature. If the impact of electromagnetic fields on the ecological environment is further extended, the subject of electromagnetic compatibility can also be referred to as environmental electromagnetics
