Figure 1: Rapid switching transitions cause interference

Every switch-mode regulator for voltage conversion causes interference. These are partly line-bound at the input side and output side of the voltage converter, but partially these are also radiated. Those interferences are mainly caused by the rapid switching edges. They are only a few nanoseconds long in modern
