Mains chokes
Mains chokes reduce the
eects of the inverter on the supplying mains.
The switching operaons in the inverter cause high-frequency interferences that will be trans-
mied unltered to the supplying mains. Mains chokes smooth the steep and pulse-like
curves coming from the Inverter and make them more sinusoidal. Moreover, the eecve
mains current is reduced and thus energy is saved.
Mains chokes can be used without restricons in conjuncon with RFI lters.
Please note that the use of a mains choke reduces the mains voltage at the input of the inver-
ter. The typical voltage drop across the mains choke is around 4 % at its rated point.
Inverters from 22 kW must always be used together with mains chokes.
