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.

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
