Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
216 words
IN AN ALTERNATING CURRENT CIRCUIT HAVING AN INPUT AND AN OUTPUT CIRCUIT IN THE LATTER OF WHCH IT IS DESIRED TO MAINTAIN A SUBSTANTIALLY CONSTANT OUTPUT VOLTAGE THROUGH THE USE OF A STABILIZING FEEDBACK VOLTAGE WHOSE AMPLITUDE AND POLARITY MAY CHANGE DEPENDING UPON THE AMOUNT OF CORRECTION NECESSARY, A FIRST SATURABLE IMPEDANCE MEANS CONNECTED ACROSS SAID INPUT CIRCUIT ACROSS WHICH A VOLTAGE WILL BE IMMEDIATELY DEVELOPED AT THE BEGINNING OF EACH HALF CYCLE, A SECOND SATURABLE IMPEDANCE MEANS AND A RESISTANCE MEANS CONNECTED IN SERIES ACROSS SAID INPUT CIRCUIT SO THAT NO VOLTAGE WILL BE DEVELOPED ACROSS THE RESISTANCE MEANS UNTIL SAID SECOND SATURABLE IMPEDANCE MEANS BECOMES SATURATED TO SAID FIRST SATURABLE IMPEDANCE MEANS BEING CONNECTED TO SAID FIRST SATURABLE IMPEDANCE, AN ERROR SIGNAL FEEDBACK CIRCUIT CONNECTED ACROSS TO BOTH THE FIRST AND SECOND SATURABLE IMPEDANCE MEANS, SAID OUTPUT CIRCUIT BEING CONNECTED ACROSS THE FIRST SATURABLE IMPEDANCE MEANS AND RESISTANCE IN SERIES AND SAID OUTPUT VOLTAGE OF SAID ALTERNATING CURRENT CIRCUIT CONSISTING OF THE SUM OF THE VOLTAGES ACROSS THE FIRST SATURABLE IMPEDANCE AND THE RESISTANCE MEANS, THE R.M.S. VALUE OF WHICH WILL CHANGE DEPENDING UPON THE AMPLITUDE AND POLARITY OF THE STABILIZING FEEDBACK VOLTAGE APPLIED TO THE ERROR FEEDBACK CIRCUIT SINCE THAT WILL ALTER THE SATURATION TIMES OF THE FIRST AND SECOND SATURABLE IMPEDANCE MEANS.
