Method and system of current sharing among bidirectional double-base bipolar junction transistors

A switch assembly comprising:

• a first bidirectional double-base bipolar junction transistor (first B-TRAN) defining an upper base, an upper collector-emitter, a lower base, and a lower collector-emitter;
• a second bidirectional double-base bipolar junction transistor (second B-TRAN) defining an upper base, an upper collector-emitter, a lower base, and a lower collector-emitter, the second B-TRAN coupled in parallel with the first B-TRAN;
• a controller;
• a first means for measuring conduction through the first B-TRAN, the first means for measuring coupled to the controller;
• a first means for controlling conduction through the first B-TRAN, the first means for controlling conduction coupled to the controller;
• a second means for measuring conduction through the second B-TRAN, the second means for measuring coupled to the controller;
• wherein the controller is configured to:
• read a value indicative of conduction through the first B-TRAN;
• read a value indicative of conduction through the first B-TRAN;
• and
• adjust, by way of the first means for controlling, current flow through the first B-TRAN, the adjustment responsive to the value indicative of conduction of the first B-TRAN being different than the value indicative of conduction through second B-TRAN.
