A system for direct optical control of electronic power semiconductors
includes an optical triggering circuit at a first location, wherein said
optical triggering circuit generates an optical trigger signal, a power
circuit located at a second location remote from the first location,
wherein said power circuit includes a photoconductor that is responsive
to the optical trigger signal generated by the optical triggering
circuit, and an optical cable coupling the optical triggering circuit to
the power circuit. In operation, the power circuit is directly driven by
the transmission of the optical trigger signal from the optical
triggering circuit to the power circuit via the optical cable. Inductive
elements or transformers may be applied to facilitate triggering
performance.
