OPTICALLY-TRIGGERED POWER SYSTEM AND DEVICES

摘要

A power device is provided in an optically-triggered power system having a controller for generating electrical control signals and a converter for converting the electrical control signals to optical control signals. The power device includes a pair of terminals and a P-body region provided adjacent an N⁺ source region. An optical window is provided at least partially over the P-body region, and an N^- drift region is provided between the two terminals. The P-body region causes current to conduct between the first and second terminal through the N^- drift region when an optical control signal is incident on the optical window.
