Drive Choke

A choke is inductor which blocks higher frequency alternating current in electric circuit. A choke is nothing but a coil of insulated wire wound on a magnetic core. Drive choke is used to reduce the impact of harmonics in variable frequency drive. As variable frequency drive is a non linear load creates harmonics which increases heating of the transformer and reduces capacity of cable and transformer. Input choke is a filter for variable frequency drive and output choke is used for the long cable.


Choke is used for the protection against overvoltage on the line supply. It reduces harmonic distortion of the current produced by the drive. Choke also reduces short circuit current.

  • Protects drive.
  • Reduces Harmonics.
  • Reduces Short circuit current.
