ABSTRACT:
A power transistor switch for switching high-amperage, direct-current through a low forward impedance, consisting of a transformer which couples a control pulse through separate multifilar secondary windings to each base element of a plurality of transistors. The utilization of multiple junction transistor geometry results in a rapid transition, i.e., low transition time consistent with a low forward impedance and cost savings because of the inherent economies in multiple junction transistors, without resort to individual discrete emitter or base resistances with the power loss inherent in their use.
