Abstract
A circuit for the production of an output voltage generated based upon an input direct voltage and a given desired voltage. A series connection comprises a longitudinal regulating member, an inductor and a push-pull current transformer which produces the output voltage. The input direct voltage is fed to the push-pull current transformer. The push-pull current transformer includes a push-pull transformer having push-pull primary winding and a secondary winding. In addition, the push-pull current transformer includes switching transistors which are switched on and off in push-pull by a control circuit. The control circuit delivers a suitable cyclical changing control signal to the switching transistors. Circuitry is provided for minimizing if not eliminating spikes in the current occurring during a switching of the switching transistors. As a result, the switching transistors remain free from excessive voltages which can damage same.
