Practical EMI Control in a Power Component Design Space

Inhalt:
The control of electromagnetic interference (EMI) within switched mode power systems is a perennial topic. This article attempts to address the notion of control of conducted emissions in the context of applying Vicor Power Components in a customer application. Vicor has developed quasi-resonant topologies that mitigate noise to a great extent by design. Although there are significant noise reductions to be had using resonant topologies in SMPS, no converter is ever noise-free. Applying power modules in a way to assure compliance with CE engineering standards can often prevent unforeseen, costly delays in bringing products to market.
