Power switching and regulating circuits

Claim 1

A SWITCHING CIRCUIT FOR PROVIDING POWER CONTROL OF A HIGHLY INDUCTIVE LOAD, COMPRISING A SOURCE OF DIRECT CURRENT POTENTIAL, A SATURABLE REACTOR HAVING A PLURALITY OF WINDINGS, SAID LOAD AND A FIRST ONE OF SAID WINDINGS BEING SERIALLY CONNECTED ACROSS SAID SOURCE, SAID REACTOR BEING SATURATED IN A FIRST DIRECTION, A SWITCHING AMPLIFIER CONNECTED INSERIES WITH SAID LOAC AND SAID FIRST WINDING, ACTIVATING MEANS CONNECTED TO SAID SOURCE OF DIRECT CURRENT POTENTIAL AND SAID SWITCHING AMPLIFIER AND OPERATIVE TO CAUSE SAID AMPLIFIER TO CONDUCT AND ALLOW CURRENT TO FLOW THROUGH SAID LOAD AND SAID SERIALLY CONNECTED FIRST WINDING, THE CURRENT IN SAID FIRST WINDING BEING OPERATIVE TO CAUSE SAID REACTOR TO SATURATE IN A SECOND DIRECTION. MEANS OPERATIVE TO RESPONSE TO SAID REACTOR SATURATION IN SAID SECOND DIRECTION TO CAUSE SAID AMPLIFIER TO CEASE TO CONDUCT, A SECOND WINDING OF SAID REACTOR AND AN ASYMMETRIC IMPEDANCE CONNECTED IN SERIES ACROSS SAID LOAD, SAID SECOND WINDING AND SAID IMPEDANCE BEING OPERATIVE WHEN SAID REACTOR SATURATES IN SAID SECOND DIRECTION TO PROVIDE A CONDUCTIVE PATH FOR THE LOAD CURRENT AND ALLOW THAT CURRENT TO RESTORE SAID REACTOR TO A SATURATION STATE IN SAI FIRST DIRECTION, AND MEANS FOR SELECTIVELY ACTUATING SAID SWITCHING AMPLIFIER ACTIVATING MEANS.
