ABSTRACT:
The present invention provides a low-cost switching system that allows very high speed ON and OFF switching of a bipolar power transistor. The switching system of the present invention consists of an FET-bipolar transistor combination which unites the advantages of FET and bipolar power transistors for extremely fast switching applications. The system draws negligible steady-state drive power and still turns the bipolar transistor fast ON and fast OFF.
