| description | This invention relates generally to a driving scheme for a bipolar transistor, and more particularly to a scheme for driving a push-pull pair of bipolar transistors in a ballast inverter.
A driving circuit for bipolar transistors having a control voltage device for producing a control voltage associated with each transistor. A tertiary winding, serving as the base winding for the bipolar transistors, supplies current to the base of each bipolar transistor based on the associated control voltage. Separate feedback circuits associated with each transistor carry a feedback signal reflecting the minority carrier charge stored in the associated transistor. The control voltage associated with each transistor varies based on the associated feedback signal. |
