Overcoming EMI In Electric Vehicle Applications

According to the U.S. Bureau of Transportation Statistics, 2020 was the fifth consecutive year of growth in electric vehicle (EV) sales, and the demand is growing. Based on the first quarter numbers, the Bureau anticipates 2021 sales are on a path to surpass last year’s. 

As production ramps up, it’s clear that EVs present a number of unique challenges, including greater susceptibility to electromagnetic interference (EMI). EVs employ high-power electronics to operate the electrical engine, producing high-level, low-frequency EMI. Interference is a common problem across electronics applications, but when we consider EV applications, where safety, efficiency, and performance rely on electronics, high levels of EMI could cause dangerous complications.
