Semiconductor inverter circuit with voltage reducing means

Claim 1

AN ELECTRICAL OSCILLATOR COMPRISING: A SATURABLE TRANSFORMER HAVING A SATURABLE CORE, A FIRST AND A SECOND PRIMARY WINDING ON SAID CORE, A FIRST AND A SECOND BIAS WINDING AND AN OUTPUT WINDING ALL INDUCTIVELY COUPLED ON SAID SATURABLE CORE, INPUT MEANS INCLUDING A TERMINAL CONNECTION TO THE POSITIVE SIDE OF A D.C. SOURCE AND A GROUNDING CONNECTION, A FIRST AND A SECOND SEMICONDUCTOR DEVICE, EACH OF SAID SEMICONDUCTOR DEVICES HAVING A CONTROL ELECTRODE AND A MAIN CURRENT PATH, CONTROL MEANS INCLUDING SAID FIRST AND SECOND BIAS WINDINGS RESPECTIVELY COUPLED TO SAID CONTROL ELECTRODES AND SAID MAIN CURRENT PATHS PF SAID FIRST AND SECOND SEMICONDUCTOR DEVICES FOR DRIVING SAID FIRST SEMICONDUCTOR DEVICE AND SWITCHING SAID FIRST SEMICONDUCTOR DEVICE MAIN CURRENT PATH INTO A CONDUCTING CONDITION IN RESPONSE TO THE SATURATION OF SAID MAGNETIC CORE IN ONE DIRECTION AND FOR DRIVING SAID SECOND SEMICONDUCTOR DEVICE AND SWITCHING SAID SECOND SEMICONDUCTOR DEVICE MAIN CURRENT PATH INTO A CONDUCTING CONDITION IN RESPONSE TO THE SATURATION OF SAID MAGNETIC CORE IN THE OPPOSING DIRECTION, A STORAGE CAPACITOR, A VOLTAGE DIVIDING NETWORK CONNECTED ACROSS SAID INPUT TERMINAL AND GROUNDING CONNECTION, SAID VOLTAGE NETWORK INCLUDING A TAPPING CONNECTION DIVIDING SAID NETWORK INTO A FIRST PORTION AND A SECOND PORTION, CIRCUIT MEANS CONNECTING SAID FIRST SEMICONDUCTOR DEVICE MAIN CURRENT PATH AND SAID FIRST PRIMARY WINDING ACROSS SAID FIRST PORTION AND PLACING SAID CAPACITOR IN CIRCUIT ACROSS SAID SECOND PORTION, SAID CIRCUIT MEANS ALSO CONNECTING SAID SECOND SEMICONDUCTOR DEVICE MAIN CURRENT PATH AND SAID SECOND PRIMARY WINDING IN CIRCUIT ACROSS THE SECOND PORTION OF SAID VOLTAGE DIVIDING NETWORK, SAID FIRST AND SECOND SEMICONDUCTOR DEVICES BEING ALTERNATELY SWITCHED INTO A CONDUCTING CONDITION IN REPSONSE TO THE SATURATION OF SAID SATURABLE CORE AND CAUSING SAID FIRST AND SECOND PRIMARY WINDINGS TO BE ALTERNATELY ENERGIZED FROM SAID UNIDIRECTIONAL CURRENT SOURCE AND FROM SAID STORAGE CAPACITOR TO PRODUCE AN ALTERNATING VOLTAGE IN SAID OUTPUT WINDING.
