Basics of Conducted Emissions Testing for Switch-Mode Power Supplies

Bourns has developed an informative guide on performing conducted emissions testing using a low-EMI (Electromagnetic Interference) DC-DC converter solution. It provides the theory behind Line Impedance Stabilization Networks (LISN), conducted emissions testing apparatus and Electromagnetic Compatibility (EMC) standards - specifically CISPR 25. Additionally, a detailed explanation on how to obtain and interpret results is given.
