Optimize EMC of DC-DC Converter with GND Plane, Filters, Gate Resistor and Spread Spectrum

A boost converter is optimized electromagnetically (EMC-aware). For this we use a continuous GND plane, place filters correctly, reduce the switching speed and try the spread spectrum technique. The individual methods are explained so that you can improve your DC-DC converter.

Interesting video! Could I have a question if those methods are effective with buck convertor?

[@koodreitz]

Sure. A good layout, the use of right filters, and slow switching - all these methods can also be applied to a step-down converter in order to decrease EMI.

Nice video. Demonstration of effects of ground plane. I am not a fan of spread spectrum techniques. It is only spreading the same level of noise over different frequencies. You are only fooling the measurement equipment. Not lowering noise in my opinion.

[@ife.tugraz]

The main idea of spread spectrum techniques is not lowering the noise, but spreading the noise frequencies over a larger freqzency range to avoid freqzency peaks.
