Common-Mode Current

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 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.

The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.

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.
