Abstract:
1. A single bias integrated thyristor, comprising: an optical thyristor core including three p-n junctions between an anode and cathode; an optically isolated transistor switched in series with one of said anode and said cathode and being biased by a single power bias source that powers the optically isolated transistor without any separate low voltage bias; a self or optically triggered gate switch biased by said single power bias source without any separate low voltage bias and connected to said integral optically isolated transistor connecting a load to a gate region to the optical thyristor core, wherein said self or optically triggered gate switch turns on a finite period after said optically isolated transistor turns off to initiate thyristor turn-off and ensure a unity gain turn-off of the thyristor; and an optically exposed gate region for receiving radiation.
