Design and Implementation of a New Drive Circuit of Monolithic Emitter-Switching Bipolar Transistor (ESBT)

This paper introduces a kind of monolithic emitter switched bipolar transistor (ESBT) for three-phase rectifier applications and other high voltage applications. This paper proposes an improved driving circuit, combining the soft switch circuit. We made a flyback circuit prototype which the rated power is 80W, and the maximum input voltage is 800V, and compared with the existing driving circuit.
