Introduction
Designing for electromagnetic compatibility (EMC) is one of the most difficult challenges for electronic system designers. Almost all-electronic equipment is required to meet one or more EMC standards at the system or product level. One of the most challenging subsystems when speaking about EMC is the power supply or in this case the dc/dc power module.
