5.2 Input chokes

The three-phase mains choke is strongly recommended in order to:
- limit the RMS input current of the ADV100 inverter.
- increase the life of intermediate circuit capacitors and reliability of input diodes.
- reduce the harmonic current distortion absorbed by the mains to typical values of 70% (at the rated current).
Mains chokes are optional from size 1040 to size 3220; on bigger sizes the choke is integrated in the DC link.

To reduce the line current THD even more (< 35%), use DC chokes wired between terminals C1 and C.

Refer to the Gefran Accessories catalogue (1S9I09) for choke weights and dimensions.

5.3 AC output chokes

Output chokes are used to reduce dv/dt of power modules (IGBT). Voltage fronts can cause damage to motor isolation
systems or, if the motor cables are long (normally more than 100 m) or highly capacitive, they can cause drive malfunc-
tions and repeated signalling of overcurrent (OC) or desaturation (DESAT) conditions. The output chokes are listed in
the table below:

5900
Note!
With the inverter operated at the rated current and a frequency of 50 Hz, the output chokes cause a voltage drop of approx. 2% of the output voltage.
Refer to the Gefran Accessories catalogue (1S9I09) for choke weights and dimensions.
