A REGULATED POWER SUPPLY CIRCUIT COMPRISING: A SOURCE OF D.C. ENERGIZING VOLTAGE, AN INVERTER CIRCUIT HAVING AN INPUT TO WHICH D.C. ENERGIZING CURRENT IS FED AND AN OUTPUT HAVING AN OUTPUT AT WHICH A SQUARE WAVE A.C. VOLTAGE OF A GIVEN FREQUENCY IS DEVELOPED BY THE INVERTER CIRCUIT, THE AMPLITUDE OF THE A.C. VOLTAGE BEING A FUNCTION OF THE MAGNITUDE OF THE D.C. VOLTAGE FED TO THE INPUT THEREOF, A CURRENT CONTROL DEVICE HAVING LOAD TERMINALS AND A CONTROL TERMINAL WHICH RENDERS SAID LOAD TERMINALS RELATIVELY CONDUCTIVE AND NON-CONDUCTIVE IN ACCORDANCE WITH THE POLARITY OF A CONTROL SIGNAL FED THERETO, FILTER CIRCUIT MEANS FOR CONVERTING A PULSATING D.C.TO A RELATIVELY STABILIZED D.C. AND HAVING AN OUTPUT CONNECTED TO THE INPUT OF SAID INVERTER CIRCUIT, MEANS CONNECTING SAID LOAD TERMINALS OF SAID CURRENT CONTROL DEVICE IN SERIES BETWEEN SAID SOURCE OF D.C. ENERGIZING VOLTAGE AND THE INPUT OF SAID FILTER CIRCUIT MEANS, MEANS CONNECTING THE OUTPUT OF SAID FILTER CIRCUIT MEANS TO THE INPUT OF SAID INVERTER CIRCUIT, WHEREBY THE D.C. VOLTAGE FED TO THE LATTER INPUT IS A FUNCTION OF THE TIME SAID CURRENT CONTROL DEVICE IS IN A CONDUCTIVE STATE, A GATED DIODE HAVING ANODE, CATHODE AND CONTROL TERMINALS, MEANS CONNECTING SAID OUTPUT OF SAID INVERTER CIRCUIT IN SERIES BETWEEN SAID CONTROL TERMINAL OF SAID CURRENT CONTROL DEVICE
