ABSTRACT:
In order to prevent pulses induced in the excitation winding of a saturable reactor due to load current in the main winding from causing partial demagnetization of the core, a compensating coil of the same number of turns as the excitation winding is mounted on the core to generate pulses equal and opposite to the induced pulses. The compensating coil pulses are applied across an inductor connected in series with the main winding. A diode in series with the compensating coil prevents the excitation current from flowing through the coil.
