Overview
Output reactor
Output reactors reduce the rate of voltage rise (
dv/dt
) and the
height of the current peaks, and enable longer motor cables to
be connected.
Owing to the high rates of voltage rise of the fast-switching
IGBTs, the capacitance of long motor cables reverses polarity
very quickly with every switching operation in the inverter.
As a result, the inverter is loaded with additional current peaks
of substantial magnitude.
Output reactors reduce the magnitude of these additional peaks
because the cable capacitance reverses polarity more slowly
across the reactor inductance, thereby attenuating the ampli-
tudes of the current peaks.
When using output reactors, the following should be observed:
•
Max. permissible output frequency 150 Hz
•
Max. permissible pulse frequency 4 kHz
•
The output reactor must be installed as close as possible to
the Power Module
Two output reactors are to be provided to increase the permissi-
ble cable lengths.
When connecting the Power Modules to IT networks, the use of
an output reactor is recommended to avoid an overcurrent shut-
down in the event of a ground fault.
