HIGH EFFICIENCY PUSH-PULL INVERTERS ABSTRACT OF THE DISCLOSURE High efficiency push-pull inverters minimize undesirable energy losses usually resulting from simultaneous conduction and imperfect switching of the transistor switching means. In each of the disclosed circuits, a saturable inductor and a diode are connected in parallel and across the base- emitter junction of each transistor. Voltage on the base of each transistor causes its associated saturable inductor to saturate, and the saturated inductor then terminates the flow of base current and provides a path for rapid evacuation of the charge carriers stored in the transistor base-emitter junction in order to render the transistor rapidly non-conductive. Each diode provides a drain path for current continuing to flow through its associated saturable inductor after junction evacua- tion. A novel triggering means initiates oscillation of the inverters. Also disclosed are feedback means operable to prevent premature transistor conduction and a capacitor connected between the collectors of the inverter transistors operable to restrain the rate of change of transistor collector voltage, both of these features also serving to minimize energy dissipa- tion.
