These protect the power semiconductors in case of high-energy, short-term vol-
tage peaks in the grid and dissipate the energy in the choke in case of a grid dis-
connection.
x Grid-side overvoltage protection (class III)
Protection against atmospheric overvoltages (e.g. caused by remote strikes du-
ring thunderstorms).
x Grid-side overvoltage protection (class II)
