What is EMC?
EMC (Electro Magnetic Compatibility): Literally translated as “electromagnetic compatibility”, it refers to the ability of the electromagnetic energy generated by the equipment to neither interfere with other equipment, nor to interfere with the electromagnetic energy of other equipment. EMC includes EMI and EMS.
EMI (Electro Magnetic Interference): Literally translated as electromagnetic interference, it refers to the electromagnetic disturbance it emits to the outside world. This is a compound word, we should consider “electromagnetic” and “interference” separately. The so-called “interference” refers to the two-layer meaning of the performance degradation of equipment after interference and the source of interference to the equipment. The first meaning is like thunder and lightning causing noise on the radio, snowflakes appearing on the TV screen after a motorcycle is driving nearby, and radio sounds are heard after picking up the phone, etc.
EMS (Electro Magnetic Susceptibility): Literally translated as “electromagnetic susceptibility”, it means the ease with which electromagnetic energy can cause performance degradation. To make it easy to understand, we compare electronic devices to people, and electromagnetic energy to cold viruses. Sensitivity is whether or not you are susceptible to catching a cold. If you are not susceptible to catching a cold, it means that you have strong immunity, which is the English word Immunity, which means strong resistance to electromagnetic interference.
