Driver circuit using diodes to control the minority carrier storage effect in switched transistors

Claim 1

In switching circuitry wherein each one of a pair of like transistors is repetitively switched on and off during mutually exclusive periods of time in response to driving signals consisting of a pair of complementary rectangular waves, the improvement comprising: a. oppositely poled first and second unidirectional conducting means connected to a control electrode of a first one of a pair of like transistors to be switched on and off, the voltage drop across the first unidirectional conducting means, when conducting, being less than the voltage drop of the second unidirectional means, when conducting; b. similarly oppositely poled third and fourth unidirectional conducting means connected to a control electrode of a second one of the pair of like transistors, the voltage drop across the third unidirectional conducting means being, when conducting, equal to the voltage drop across the first unidirectional conducting means, when conducting, and less than the voltage drop across the fourth unidirectional conducting means, when conducting; and c. center-tapped transformer means for applying a first one of a pair of complementary rectangular waves to the first and the second unidirectional conducting means and for applying a second one of the pair of complementary rectangular waves to the third and fourth unidirectional conducting means.
