Arrangement for controlling a direct voltage source

Claim 1

A CIRCUIT ARRANGEMENT FOR MONITORING A DIRECT VOLTAGE SOURCE COMPRISING A CORE OF MAGNETIZABLE MATERIAL, A FIRST WINDING MEANS INDUCTIVELY COUPLED TO SAID CORE AND CONNECTED TO THE DIRECT VOLTAGE SOURCE FOR GENERATING A MAGNETIC FLUX OF A GIVEN MAGNITUDE AND GIVEN DIRECTION IN SAID CORE AS LONG AS SAID DIRECT VOLTAGE SOURCE TRANSMITS A GIVEN CURRENT, A SECOND WINDING MEANS INDUCTIVELY COUPLED TO SAID CORE FOR TRANSMITTING OUTPUT SIGNALS RELATED TO THE CONDITION OF THE DIRECT VOLTAGE SOURCE, A THIRD WINDING MEANS INDUCTIVELY COUPLED TO SAID CORE FOR RECEIVING CURRENT PULSES FOR GENERATING PULSES OF MAGNETIC FLUX HAVING A MAGNITUDE GREATER THAN SAID GIVEN MAGNITUDE AND OPPOSITE SAID GIVEN DIRECTION, FOURTH AND FIFTH WINDING MEANS INDUCTIVELY COUPLED TO SAID CORE, AND MEANS FOR REGENERATIVELY COUPLING SAID FOURTH WINDING MEANS TO SAID FIFTH WINDING MEANS FOR CAUSING SAID FIFTH WINDING TO GENERATE A PULSE OF MAGNETIC FLUX IN SAID CORE HAVING A DIRECTION OPPOSITE TO SAID GIVEN DIRECTION FOR EACH CHANGE OF MAGNETIC FLUX SENSED IN SAID CORE BY SAID FOURTH WINDING MEANS RESULTING FROM THE INTERACTIONS OF THE MAGNETIC FLUXES GENERATED BY SAID FIRST AND THIRD WINDING MEANS.
