Claims

1. VOLTAGE OR CURRENT REGULATOR APPARATUS FOR REGULATING THE VOLTAGE OR CURRENT IN A CIRCUIT IN WHICH AN ALTERNATING CURRENT FLOWS, COMPRISING AT LEAST ONE ELECTRICAL CURRENT SOURCE;

SWITCH MEANS ASSOCIATED WITH THE SAID SOURCE, WHICH SWITCH MEANS IS TRIGGERABLE INTO A CONDITION IN WHICH IT CONNECTS THE SOURCE INTO THE CIRCUIT;

SAID SWITCH MEANS COMPRISING A SWITCH DEVICE WHICH REQUIRES TO BE TRIGGERED IN EACH CYCLE OF THE SAID ALTERNATING CURRENT TO MAINTAIN THE SWITCH MEANS IN THE SAID CONDITION, AND CONTROL MEANS OPERATIVELY CONNECTED TO THE SAID DEVICE AND RESPONSIVE TO THE ZERO CURRENT INSTANTS OF THE ALTERNATING CURRENT IN THE SAID CIRCUIT TO REPEATEDLY TRIGGER THE SAID DEVICE IN PREDETERMINED TIME RELATIONSHIP WITH THE SAID ZERO CURRENT INSTANTS TO CONNECT THE SAID SOURCE IN THE CIRCUIT FOR SUBSTANTIALLY THE WHOLE CYCLE OF EACH OF SELECTED CYCLES OF THE ALTERNATING CURRENT IN THE SAID CIRCUIT.
