OPERATION OF DOUBLE-BASE BIPOLAR TRANSISTORS WITH ADDITIONAL TIMING PHASES AT SWITCHING TRANSITIONS

摘要

Methods and systems for operating a double-base bidirectional power bipolar transistor. Two timing phases are used to transition into turnoff: one where each base is shorted to its nearest emitter/collector region, and a second one where negative drive is applied to the emitter-side base to reduce the minority carrier population in the bulk substrate.
