Abstract

Analysis of the turnoff process of SCR plays an important part in the design of SCR circuits. A simple computer model is developed to simulate the SCR turnoff process. This is based on the recovered charge characteristics given in the data sheets and the empirical results. Approximations involved in the simulation of stored charge are indicated. Computer analysis gives better understanding of the SCR reverse current, voltage and their effect on the circuit performance.
