Abstract

863,658. Transistor inverter circuits. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 17, 1958 [Dec. 31, 1957], No. 40692/58. Class 40(6) [Also in Group XXXV] An inverter of the type comprising two alternately conductive transistors which are connected to a feedback transformer so as to reverse conduction each time the transformer saturates, has a capacitor connected in circuit with the transformer to form a resonant circuit which maintains the saturation condition for a time after one transistor is cut-off and thereafter reverses the transformer current flow so as to render the other transistor conducting. Fig. 1 shows a transistor inverter comprising two transistors which conduct alternately and so provide a high voltage to a capacitive load 9a in the form of an electro-illuminescent device. When transistor 33a becomes conducting the current through the transistor and the upper half of the primary winding of a transformer 11a commences to increase. This induces a voltage in the secondary winding 27a through which charges the load 9a and causes an increase in current to flow through the primary winding 53a of transformer 49a. This increasing current induces a voltage in the secondary winding to maintain transistor 33a conducting until the transformer 49a saturates whereupon the secondary voltage falls to zero and transistor 33a cuts off. The load 9a then commences to discharge resonantly through an inductor 83 and the primary winding 53a maintaining both transistors cut-off until the curent through the resonant circuit reverses, whereupon a voltage is induced through, the secondary winding 69a which causes transistor 35a to conduct so that the voltage applied to the load is reversed. The output voltage is of sine wave form but if inductor 83 is removed a square wave output is produced (Fig. 1, not shown). When the load is of inductive impedance it is placed in the position of inductor 83 and a capacitor replaces load 9a.
