ABSTRACT:
A D-C voltage converter for controlling the voltage at an inductive load. The circuit is provided with a pulse transformer having first and second primary windings, a secondary winding, and a demagnetizing winding. The second primary winding receives a D-C voltage from a main D-C voltage supply by means of a controlled thyristor. The thyristor in combination with the first primary winding induce currents in the second primary winding and the secondary winding, which maintain a charge on a battery and which supply the inductive load. Electrical energy from the battery is used to produce a countervoltage for extinguishing a thyristor. In addition, circuitry is provided for extinguishing the conduction of the controlled thyristor.
