Why Do We Need a Power Line Filter and Where to Place It?

NettetSmaller kW drives can be particularly susceptible to supply variations and also to connection to supplies with low impedance / high short circuit current and line chokes are recommended in these cases. Notes: Fitting an Input line reactor will cause a drop in the incoming supply voltage level to the AC drive (generally between 2 and 5%). NettetThe drive operates with a high degree of stability – even during line supply fluctuations; Improved EMC and grid (harmonics) performance due to integral DC choke (FSA-FSG, up to 400 hp / 250 kW) SINAMICS G120X's operating temperature extends from -4°F to 140°F (-20°C to 60°C )(depending on the exact version). t1 studio

NettetDo not connect ACS355 drives to the same DC bus with other drive types. The only exception is ACSM1 drives. Other ABB drive types have internal reactors in the DC circuit or AC chokes on the supply side. Connecting different drive types to the AC line causes supply current unbalance, which may seriously damage the drives.

NettetTo evaluate the influence of an additional AC line reactor on a drive already equipped with a DC choke, the maximum input lines voltage unbalance of 2.1% is kept constant. The additional AC line reactor value is increased from 0 to the same value already used to compare the DC choke and AC line reactor in the previous section. NettetAdvantages of using a DC link choke. Reduces the harmonic currents therefore improves the power factor of a drive. Increases the lifetime of the capacitors from typical 6 years under full load to 10 years under full load. Produces less heat than an equivalent AC choke resulting in better efficiency and less panel heating.
