Chokes are resistors with a high inductive and small ohmic component.
For example, you will find application as
Limitation of the short-circuit current or starting current to a specified value. Damping of harmonics or interference voltage.
Reduction of the ripple or extension of the current flow duration with pulsating direct current.
Reduction of the steepness of the current rise and thus limitation of the peak currents during commutation.
Filter circuit choke:
Protection of compensation systems against impermissible harmonics.
