Power Tip 48: Tame conducted common-mode emissions in isolated switchers – Part 2
Robert Kollman of Texas Instruments continues our discussion of common-mode currents which started in Power Tip 47.

We discussed that we can return common-mode currents to their source by using a chassis capacitor, which also reduces the source impedance of the noise. However, there is a safety limit as to how much capacitance we can use, which determines the remainder of the common-mode filter.
