Development and Investigations of Light Triggered Thyristors for Pulse Application

摘要

This report presents the results of development and investigations of power Light Triggered Thyristorsrn(LTT) for pulse applications. LTTs are often used in high voltage applications where a seriesrnconnection of devices is required [1]. Light triggered thyristors should be preferred as solid-staternswitches because of the advantage of high voltage blocking and the easy way of light triggering [2,3].rnLTTs allow simple and reliable circuits in power transmissions, and super-high power pulserncommutation units. The design of power fast LTT with 4” basic unit for pulse commutation up to 100rnkA and 700 μs is presented.
