INTRODUCTION :

A. Need for Highest Power Thyristors

There is a growing need in the market for thyristors of the highest
voltage design that can endure heavy fault currents as experienced in new
electrical power systems or operating in the pulse power mode as for mili-tary
weapons and other government laser and magnet supplies. An example
of a milestone already past is the installation of 100 mm thyristors on the 500
kV AC transmission line of BPA-Slatt substation: thyristor controlled series
compensation, {TCSC} [1]. In that application, the most demanding pa-rameter
to meet was the high multi-cycle asymmetrical fault current. It was
necessary to predict fault withstand capability [2] according to the highest
available standard as designated faults were to be expected and not consid-ered
as rare occurrence. Pulse power duty, on the other hand, are single
shot events with durations usually less than 8.3 ms and peak current much
higher than normally encountered.
When circuit designers encounter more of these stringent surge duty
applications, they are sure to realize the inadequacy of normally published
surge current data. Moreover if they are to make an evaluation and choose
from contending devices using non-repetitive surge current, I TSM ratings as
an essential criteria, they will be mislead. Consequently one should make
specific inquires to thyristor manufacturers so as to develop a mutual under-standing
of the real surge current requirement. including details about verifi-cation
testing and life expectancy.
