A physically-based lumped-charge SCR model

A physical silicon-controlled rectifier (SCR) model is developed by using the lumped-charge modeling technique to simplify device physics. The model is based on fundamental semiconductor equations and includes most important SCR characteristics; yet it is simple enough to use in circuit simulators. This SCR model is the first to provide correct turn-on and turn-off waveforms for simulation of power switching circuits.<<ETX>>
