Mains chokes
Mains chokes or mains filters are always required for some
inverters because otherwise the permissible rated data of the
components used might be exceeded by the mains currents.
A mains choke is an inductor that is connected to the mains
cable of the inverter. Using a mains choke offers the following
advantages:
ƒ
See Rated data
ƒ
Reduced system perturbation:
The wave form of the mains current is a closer approxim-
ation of a sine wave.
ƒ
Mains chokes can be used without restriction together
with RFI filters and/or motor filters.
ƒ
Reduced r.m.s. mains current:
ƒ
Please note:
Reduction in mains, line and fuse load
When using a mains choke, the maximum achievable
output voltage of the axis modules is slightly reduced.
ƒ
Longer inverter service life:
Reducing the AC load on the electrolytic capacitors in the
DC bus increases the service life of the capacitors.
ƒ
DC-bus connection with multiple supplies
The DC-bus connection can be used to exchange energy
