Optical triggering of power thyristors (3)
Abstract
Light activated high voltage auxiliary thyristors were developed for blocking voltages until to 4 kV, and additionally suitable packages and optical coupling components. Turn-off times can be reduced without considerable deterioration of the trigger sensitivity. The integration of potential limiting diodes, Al-diffusion, compact device technology, and the problem of trigger delay times were also investigated.
