A 10-kW series resonant converter design, transistor characterization, and base-drive optimization

The Westinghouse D60T and development D7ST transistors are characterized for use as switches in resonant circuit applications. A base drive circuit to provide the optimal base drive to these transistors under resonant circuit conditions is developed and then used in the design, fabrication and testing of a breadboard, space-borne-type 10-kW series resonant converter.
