Common-Mode Current

Without much effort and expense, it is possible to perform pre-compliance testing in a manner that saves considerable time and money without commercial or financial risks associated with purchasing a full-compliance test facility.

This article discusses the distribution of a PCB return current underneath top trace for the microstrip configuration. Next month’s article will discuss the distribution for the stripline configurations.

This article discusses the common-mode and differential-mode radiation from cables and presents the measurement results from the SMPS connecting wires.

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.

This tutorial article focuses on the skin depth phenomenon in good conductors. We begin with the uniform plane propagation, leading to the wave equations and their solutions in different media.
