Electromagnetic Compatibility Print Electromagnetic Compatibility (EMC) is a branch of electrical sciences. The purpose of electromagnetic compatibility is to keep the unintentional propagation and reception of electromagnetic energy under control. EMC ensures the compatibility of a device or a system in its electromagnetic environment. Correct operation of a device includes to minimize the transmission of unwanted electromagnetic interference as well as to reduce the potential vulnerability by electromagnetic interference acting from the outside. EMC is often referred to as the control of EMI (Electromagnetic Interference) in order to avoid/prevent electromagnetic interference effects. Prev Next
