DRIVER CIRCUIT USING DIODES TO CONTROL THE MINORITY CARRIER STORAGE EFFECT IN SWITCHED TRANSISTORS

摘要

An improved driver circuit for a pair of switching transistors in a DC-DC converter or a DC-AC inverter is shown. The illustrated circuit includes a switchable constant current source coupled through a transformer and semiconductor diodes to the switching transistors. The diodes are arranged so that, as long as minority carrier current flows in either one of the switching transistors, the other is prevented from responding to a switching signal from the constant current source.
