ABSTRACT:
A push-pull converter has a transformer provided with a primary winding and a secondary winding. A capacitive element is connected between the input terminals of the primary winding, and two switch elements are arranged between a respective input terminal of the primary winding through an inductor and a supply input of the converter. The current-input terminals of the switch elements are connected to one another, and the current-output terminals of the switch elements are each connected to the respective input terminals of the primary winding. The switch elements are made up of NPN bipolar transistors connected in common-collector configuration. The push-pull converter is particularly suited for driving a cold-cathode fluorescent lamp.
