The mains supply chokes compensate voltage fluctuations and simultaneously increase the efficiency. Applying the appropriate power choke an overall efficiency of up to 90% can be achieved.

The use of a power choke is especially recommended for main circuits where high capacities are switched, for example via thyristors.
