high-energy peak. To this purpose, varistors are more suitable. As a useful tip, in case a discrete line filter is
implemented, it is recommended to place the TVS after the common mode choke: as a CMC acts like an impedance
barrier (from the signals propagation point of view) perturbations in the internal DC bus could become fast and
short overvoltages when reflected in the CMC. If any of this reflections could reach a dangerous level, the TVS would
get rid of it.
With all this, the following generic solution is proposed:
