Chokes are inductive components in the field of electrical engineering. They are mainly used in the field of power supply of electrical devices or systems, in power electronics as well as in low and high frequency technology. Line chokes consist of at least one winding of a current conductor through which the full load current flows. The winding is usually wound on a coil carrier and consists of a soft magnetic core. Chokes work with the so-called self-induction and can therefore be used in various areas of electrical engineering. Chokes can thus be used for suppression, radio interference suppression, commutation, current limiting, suppression of unwanted frequencies or for energy storage in switching regulators and switching power supplies.
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.
