What is EMC / EMI?


Electromagnetic compatibility (EMC) is the branch of electrical engineering concerned with the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment.

All electrical and electronic devices, or installations, influence each other when either interconnected or placed in close proximity. This can be seen as interference between your television or radio, for example, and a nearby washing machine or overhead power line. EMC requirements are designed to keep these side effects under reasonable control. Similarly, in cars many elements are managed electronically and any interference could cause them to malfunction. Therefore, it is important to evaluate these systems for quality and functional safety with the help of EMC regulations.

Internationally, the EMC standards have been developed for two purposes. Firstly, they regulate the electromagnetic emissions from a piece of equipment, and secondly they ensure the immunity of that equipment to electromagnetic interference
