General principles of EMC characterisation and interference suppression

Electromagnetic compatibility (EMC) is the ability of equipment to withstand a certain amount of electromagnetic interference without contributing themselves excessive amounts of electromagnetic energy into the environment. EMC thus involves issues of susceptibility and emission, covers a very wide frequency spectrum, and must be designed into virtually all types of equipment incorporating any kind of electrical supply. Addresses topics in EMC of interest to the power electronics designer with emphasis on basic principles. The author discusses conducted and radiated interference, bandwidth, pulsed and high frequency signals, shielding, filtering and grounding and EMC as part of an optimised design
