Abstract :
A new type of light activated bi-directional thyristor device, which is well suited for control of full wave ac power, is presented. This device consists of two thyristors connected in inverse parallel and one or two light emitting diodes provided between the thyristors, which are optically coupled so that either thyristor can be triggered by the light signal from the LED. It has an improved commutating dv/dt characteristic of 100 ν/μs and has ratings of 1,000 V for blocking voltage and 100 A for current carrying capability.
