摘要

An inverter (1) with a sine filter comprise a long choke (5) and a capacitive network (6) and additional current-compensated choke coils (7) for a voltage-impressed inverter together with the inverter in a housing. The current-compensated choke is connected after and outside the common housing of the inverter and sine filter.
