Abstract:

This paper describes a general computer model for a high power SCR that gives an accurate simulation of all important static and dynamic SCR performance characteristics. This high power SCR model has been applied to four different SCRs with surge current ratings in excess of 1000 amps. These are the Westinghouse T527, the IRC 125PM, and the GE C354A and C358E SCRs. All of these devices use the shorted emitter construction. All but one C354A have some form of amplifying gate. In every case, excellent correlation between the measured and computer simulated SCR performance characteristics is obtained. The fact that the four devices modeled have diverse characteristics, geometries, and construction features indicates that the high power SCR model can be universally applied to other SCRs. The high power SCR model described in this paper is an improved version of the T527 SCR model previously developed by the writers and published in Technical Report AFAPL-TR-75-106. Author
