Regulated power supply circuit utilizing controlled rectifier

Claim 1

A REGULATED POWER SUPPLY CIRCUIT COMPRISING, IN COMBINATION: A CONTROLLED RECTIFIER COUPLED TO A SOURCE OF ALTERNATING CURRENT AND ADAPTED TO SUPPLY INTERMITTENTLY FLOWING, UNIDIRECTIONAL CURRENT TO A LOAD; A STORAGE CAPACITOR CONNECTED IN A SERIES LOOP CIRCUIT WITH SAID CONTROLLED RECTIFIER AND THE SOURCE OF ALTERNATING CURRENT; MEANS FOR COUPLING A LOAD IN PARALLEL WITH SAID STORAGE CAPACITOR, WHEREBY IN ITS STEADY-STATE OPERATION SAID STORAGE CAPACITOR RECEIVES DISCRETE PULSES OF CHARGING CURRENT FROM SAID CONTROLLED RECTIFIER AND ALTERNATELY SUPPLIES PULSES OF CURRENT TO THE LOAD; CONTROL MEANS FOR PERIODICALLY INITIATING CONDUCTION OF SAID CONTROLLED RECTIFIER; AND A FEEDBACK CIRCUIT COUPLED ACROSS SAID STORAGE CAPACITOR, AND INTERCOUPLED WITH SAID CONTROL MEANS; SAID FEEDBACK CIRCUIT INCLUDING MEANS FOR PRODUCING A DIRECT CONTROL VOLTAGE WHOSE AMPLITUDE OF THE RIPPLE TIALLY PROPORTIONAL TO THE AMPLITUDE OF THE RIPPLE VOLTAGE OCCURRING ACROSS AND STORAGE CAPACITOR AT THE FREQUENCY OF SAID PULSES RECEIVED FROM SAID CONTROLLED RECTIFIER; SAID FEEDBACK CIRCUIT ALSO INCLUDING MEANS FOR APPLYING SAID DIRECT CONTROL VOLTAGE TO SAID CONTROL MEANS.
