Silicon Controlled Rectifier Large Signal Model.

摘要

Experimental measurements and a computer model of the transient behavior of standard low and intermediate power SCR's are described. The forward current through the device is monitored as the gate is triggered, with an initially applied forward voltage. The anode current as a function of time has been measured for fixed gate pulse duration, with gate pulse amplitude as a parameter. A computer model, using exponential functions to describe the anode current as a function of time, has been developed and is compared with the experimental results.
