Electromagnetic compatibility: bench testing for power assemblies

Abstract

There are many electromagnetic compatibility (EMC) requirements that must be met for information technology equipment (ITE). These requirements must be met by any power assemblies that are part of the final product. EMC bench testing of these power assemblies can be performed prior to integration into final products so that problems can be identified and engineering changes made early in the design cycle. The test configurations and procedures needed to perform the EMC bench testing have many elements that take into consideration where the assemblies will be used, the number of assemblies, and the EMC requirements to be met.
