Conducted emissions failures, across commercial, industrial, automotive, and defense sectors, remain consistently ranked among the top three most common EMC test failures. This is somewhat surprising, given that filtering techniques are well understood and widely used by design engineers. Yet, many products continue to struggle during conducted emissions … [Read more...]
Insertion Loss and Filter Performance
Background Filters are almost always a part of electronics design. Design engineers design a filter to achieve certain attenuation in specified frequency range. There are many types of filters, such as high pass, low pass or bandwidth. Popular filter configurations include L-C, C-L-C (π) or L-C- L (T). It is safe to say that when it comes to filter design, the discussion of … [Read more...]
Demystifying EMC in an Electric Vehicle’s Drive Unit
1. Introduction The past decade has witnessed both a leap forward in technology and market expansion of the global electric vehicle (EV) industry [1]. With Tesla leading the market, followed by traditional vehicle original equipment manufacturers (OEMs) such as Volkswagen, PSA, and Toyota, to name just a few, the electrification of the automotive industry has been advancing at … [Read more...]
