Input regulated power supplies

Claim 1

IN A DIRECT CURRENT REGULATED POWER SUPPLY, THE COMBINATION OF, A POWER TRANSFORMER INCLUDING PRIMARY AND SECONDARY WINDINGS, RECTIFIER AND FILTER MEANS CONNECTED TO SAID SECONDARY TO PROVIDE FILTERED DIRECT CURRENT TO OUTPUT MEANS, TWO BACK-TO-BACK SILICON CONTROLLED RECTIFIERS INCLUDING GATE ELEMENTS CONNECTED TO SAID PRIMARY FOR CONTROLLING ALTERNATING CURRENT FROM A POWERLINE TO SAID PRIMARY, A SATURABLE REACTOR PULSE GENERATOR COUPLED TO SAID GATES FOR CONTROLLING THE FIRING OF SAID SILICON CONTROLLED RECTIFIERS, A SOURCE OF REFERENCE VOLTAGE, MEANS FOR COMPARING AT LEAST A PORTION OF SAID OUTPUT VOLTAGE WITH SAID REFERENCE VOLTAGE TO PROVIDE AN ERRORS SIGNAL IN ACCORDANCE WITH THE DIFFERENCE THEREBETWEEN, MEANS FOR AMPLIFYING SAID ERROR SIGNAL, A RESISTANCE CAPACITANCE LAG NETWORK FOR DELAYING SAID AMPLIFIED ERROR SIGNAL, A SIGNAL RESPONSIVE PHASE SHIFTER COUPLED TO RECEIVE AN ALTERNATING CURRENT VOLTAGE FROM THE SILICON CONTROLLED RECTIFIERS CONNECTED POWER LINE, MEANS FOR APPLYING SAID DELAYED AMPLIFIED ERROR SIGNAL TO SAID PHASE SHIFTER TO PHASE SHIFT THE ALTERNATING CURRENT VOLTAGE APPLIED THERETO TO PROVIDE AN ALTERNATING CURRENT VOLTAGE PHASE CONTROLLED BY SAID DELAYED ERROR SIGNAL AND MEANS FOR APPLYING SAID PHASE CONTROLLED ALTERNATING CURRENT TO SAID SATURABLE REACTOR PULSE GENERATOR FOR CONTROLLING THE TIMING OF SAID PULSES IN ACCORDANCE WITH THE PHASE CONTROLLED ALTERNATING CURRENT WHEREBY THE FIRING OF SAID SILICON CONTROLLED RECTIFIERS CONTROLS THE DIRECT CURRENT OUTPUT OF SAID POWER SUPPLY.
