Calculation of lter current
I filter [A] =
Pm
Uln * √3 * ηf * ηl * ηm
Example:
Rated motor power Pm 18.5 [kW]
Motor efciency ηm 95%
Mains voltage Uln 400 [V]
Mains frequency 50 [Hz]
Inverter efciency ηl 98%
Passive lter efciency ηf 99.0%
Filter current 29.0 [A]
The rated current of the chosen lter must be ≥ the lter current calculated above:
