Horizontal Output Transistor Base Circuit Design

The recently introduced high voltage power transistor has found increasing usage in such applications as TV horizontal sweep circuits, switching regulators and other switching applications. A serious problem confronting the circuit designer is how to design circuitry so that transient switching losses are minimized. It is the purpose of this paper to discuss some of the aspects of device behavior and circuit design which can lead to optimum performance with respect to fast current fall at turn off.
