Using EMI filters to counter strong electromagnetic waves and unwanted electric currents induced in a circuit.

Electric vehicles (EVs) use several kilowatts of energy to drive the ac synchronous propulsion motor from 400-V lithium-ion (Li-ion) batteries. The dc/dc circuits used to charge the batteries generate ...

What is electromagnetic interference and what causes it? The main approaches to filtering out EMI and reducing its impact. How to evaluate EMI filters and what to know about designing them.

Compared to traditional common-mode choke solutions, Monolithic EMI filters provide significantly more RFI suppression in a substantially smaller package. A multitude of factors are conspiring to ...

Do busbars need EMI filters? Yes, they do. Just because they’re large imposing structures, they can cause interference in other systems if you don’t measure the EMI and take steps to get it under ...
