Preregulator circuit

Claim 1

A REGULATED POWER SUPPLY COMPRISING: MEANS ADAPTED TO RECEIVE AN ALTERNATING CURRENT ENERGY, A LOAD CIRCUIT SUPPLIED WITH DIRECT CURRENT ENERGY THEREFROM, A SWITCH HAVING A PAIR OF CURRENT CONDUCTING ELECTRODES INCLUDED IN SAID CIRCUIT AND A GATE ELECTRODE, A STORAGE ELEMENT, MEANS INCLUDING SAID SWITCH CONNECTED TO SAID STORAGE ELEMENT FOR CHARGING SAID STORAGE ELEMENT FROM SAID ALTERNATING CURRENT ENERGY, A REGULATING DEVICE CONNECTED IN SAID LOAD CIRCUIT, A TIMING CAPACITOR, MEANS FOR PERIODICALLY CHARGING SAID TIMING CAPACITOR AT A VARYING RATE, MEANS FOR VARYING THE MAGNITUDE OF SAID RATE INCLUDING MEANS FOR SUPPLYING TO SAID TIMING CAPACITOR (A) A PERIODICALLY-VARYING SIGNAL RELATED IN AMPLITUDE AND SYNCHRONOUSLY RELATED IN TIME TO SAID ALTERNATING CURRENT ENERGY, (B) A SECOND SIGNAL RELATED TO VOLTAGE VARIATIONSS ACROSS SAID REGULATING DEVICE, (C) A THIRD SIGNAL RELATED TO VOLTAGE VARIATIONS IN SAID LOAD CIRCUIT, AND TRIGGER CIRCUIT MEANS CONNECTED TO SAID TIMING CAPACITOR FOR PASSING A GATING SIGNAL TO SAID GATE ELECTRODE WHENEVER THE CHARGE ACROSS SAID TIMING CAPACITOR EQUALS A PREDETERMINED VALUE, WHEREBY SAID GATING SIGNAL FROM SAID TRIGGER CIRCUIT MEANS FIRES SAID CONTROLLED RECTIFIER AT A POINT IN EACH CYCLE OF SAID ALTERNATING CURRENT ENERGY THAT IS DEPENDENT UPON THE ALTERNATING CURRENT SIGNAL MAGNITUDE, LOAD CURRENT, AND LOAD VOLTAGE.
