Power Supply
As the power part of the HMV01.1R power supply units consists of a
clocked 3-phase IGBT bridge, a mains choke KDxx will always be needed
for the mains connection. In addition, a so-called combining filter HFD will
be required.

Fig. 13-8: Mains connection via mains choke and combining filter
Basically, the HFD combining filters to be provided for the mains
connection of the power supply units have two tasks:
•
to suppress the current leakages from parasitic capacities of the
construction (motor cable, winding capacities) and
