ABSTRACT:
A base drive circuit particularly well adapted for use with bipolar power transistors in high frequency power conversion systems. When utilized in a transformer isolated inverter system, the base drive circuits present a polarity insensitive input impedance which eliminates the effects of cross-conduction between base drive circuits connected to the secondary side of the transformer.
