The Ins and Outs of Frequency Spread Spectrum (Download)

May 20, 2024

Read this article online.

Frequency spread spectrum (FSS) is a technique that’s been widely used in power-conversion designs to reduce electromagnetic-interference (EMI) noise. But optimizing EMI without compromising on other aspects of the design can pose some challenges.

Many different parameters must be considered in the context of FSS design, including the modulation shape, frequency, and depth, all of which have varying impacts on the EMI spectrum. This guide runs through three different methods to evaluate FSS technologies and optimize these parameters.
