ABSTRACT:
A transistor inverter includes a pair of switching transistors each having base, emitter and collector electrodes, each of the collector and emitter circuits of which is connected between a DC voltage source through a primary winding of an output transformer, respectively, the secondary winding of which is connected to a rectifying circuit so as to produce a DC output voltage at its output. The transistor inverter also includes an input transformer with a saturable core and voltage feedback and current feedback circuits. The current feedback circuit has another transformer which controls the amount of current feedback, and the winding ratio of the primary and secondary windings is determined in connection with the current amplification factor of said first and second switching transistors in order to improve a switching speed of the switching transistors.
