Electronic regulating device

Claim 1

A REGULATING SYSTEM FOR A SOURCE OF ELECTRIC ENERGY HAVING AN ENERGIZING CIRCUIT AND A PAIR OF OUTPUT TERMINALS FOR SUPPLYING CURRENT TO A LOAD CIRCUIT, COMPRISING A SEMICONDUCTOR DEVICE HAVING CONTROL AND OUTPUT ELECTRODES, MEANS CONNECTING SAID SEMICONDUCTOR AND SAID ENERGIZING CIRCUIT IN SERIES ACROSS SAID OUTPUT TERMINALS, AN ELECTRON DISCHARGE DEVICE HAVING A CONTROL ELECTRODE AND AN OUTPUT ELECTRODE, MEANS CONNECTING SAID ELECTRON DISCHARGE DEVICE OUTPUT ELECTRODE TO SAID CONTROL ELECTRODE OF SAID SEMICONDUCTOR, A VOLTAGE COMPARISON CIRCUIT CONNECTED ACROSS SAID OUTPUT TERMINALS FOR PRODUCING A CONTROL VOLTAGE, MEANS FOR APPLYING SAID CONTROL VOLTAGE DIRECTLY TO THE CONTROL ELECTRODE OF SAID ELECTRON DISCHARGE DEVICE FOR CONTROLLING THE CONDUCTION THEREOF, A FEEDBACK CIRCUIT CONNECTED BETWEEN THE OUTPUT AND CONTROL ELECTRODES OF SAID SEMICONDUCTOR AND ELECTRON DISCHARGE DEVICES, RESPECTIVELY, THEREBY FORMING A TRIGGER CIRCUIT, A RESISTOR CONNECTED IN SERIES WITH SAID SOURCE OF ELECTRIC ENERGY AND SAID LOAD CIRCUIT, A GATE ELEMENT CONNECTED IN CIRCUIT WITH THE CONTROL ELECTRODE OF SAID ELECTRON DISCHARGE DEVICE, AND MEANS FOR APPLYING THE VOLTAGE DEVELOPED ACROSS SAID RESISTOR TO SAID GATE ELEMENT, SAID LATTER VOLTAGE OPERATING TO CONTROL CONDUCTION OF SAID ELECTRON DISCHARGE DEVICE WHENEVER THE LOAD CURRENT EXCEEDS A PREDETERMINED VALUE.
