Voltage doubler rectifier with constant voltage and variable output voltage

Claim 1

A VOLTAGE DOUBLER RECTIFIER CIRCUITRY COMPRISING AN INPUT TRANSFORMER HAVING A PRIMARY WINDING TO WHICH IS APPLIED A SOURCE OF ALTERNATING CURRENT SUPPLY VOLTAGE AND A SECONDARY WINDING, MEANS FOR ALTERNATELY CONNECTING TO GROUND THAT ONE OF THE RESPECTIVE ENDS OF SAID SECONDARY WINDING WHICH IS AT POSITIVE POTENTIAL DURING SUCCESSIVE HALF CYCLES OF SAID INPUT SIGNAL, A VOLTAGE DOUBLING NETWORK CONNECTED TO ONE END OF SAID SECONDARY WINDING, SAID DOUBLING NETWORK COMPRISING FIRST, SECOND AND THIRD SERIALLY INTERCONNECTED AND LIKE-POLARIZED DIODES CONNECTED BETWEEN THE CONNECTED ONE OF SAID SECONDARY WINDING ENDS AND A FIRST OUTPUT TERMINAL, A FIRST CAPACITOR SHUNTING THE SERIALLY INTERCONNECTED OF SAID FIRST AND SECOND DIODES, A SECOND CAPACITOR HAVING ONE TERMINAL THEREOF CONNECTED TO THE JUNCTION BETWEEN SAID FIRST AND SECOND DIODES AND THE SECOND TEMINAL THEREOF CONNECTED RESPECTIVELY TO OPPOSITE ELECTRODES OF FOURTH AND FIFTH DIODES, THE CATHODE ELECTRODE OF SAID FOURTH DIODE BEING CONNECTED TO A POSITIVE SOURCE OF THE DIRECT CURRENT VOLTAGE REFERENCED TO GROUND, MEANS FOR APPLYING A PREDETERMINED PORTION OF SAID POSITIVE DIRECT CURRENT VOLTAGE TO THE ANODE ELECTRODE OF SAID FIFTH DIODE AND A THIRD CAPACITOR AND FIRST LOAD IMPEDANCE EACH CONNECTED BETWEEN SAID FIRST OUTPUT TERMINAL AND GROUND, WHEREBY THE VOLTAGE DEVELOPED ACROSS SAID FIRST LOAD IMPEDANCE HAS A MAGNITUDE EQUAL TO TWICE THAT OF THE VOLTAGE INDUCED IN SAID TRANSFORMER SECONDARY WINDING LESS THE DIFFERENCE BETWEEN SAID DIRECT CURRENT SOURCE MAGNITUDE AND SAID PREDETEMRINED PORTION THEREOF AS APPLIED TO SAID FOURTH AND FIFTH DIODES RESPECTIVELY.
