Line Chokes

Line chokes are inductances which are connected in series to devices such as inverters and rectifiers.  Lines chokes are used widely in Drive systems, battery chargers and UPS.  They are available in both single phase and three phase designs.

Line Chokes reduce harmonics and limit surge currents.  They also protect rectifiers from voltage fluctuations in the mains supply (dv/dt phenomena).  Line chokes also reduce the peak currents drawn by inverters and reduce the starting current drawn by motors.
