Advanced power-converter features for reducing EMI

Electromagnetic interference (EMI) is a hot topic in automotive and industrial power electronics due to the addition of new emissions standards and the tendency toward higher-frequency switching regulators. Generally, low-frequency EMI is expensive to filter, and high-frequency EMI is often a mystery to find and difficult to address. Modern EMI features target these issues to significantly reduce the cost and effort needed to pass EMI standards. This presentation examines how to pass EMI at different frequency bands with new features provided by modern, industrial buck converters.
