Digital Simulation of Solid State Circuit Breaker using Simulink

A. Kalai Murugan, Dr.R. Raja Prabu

Abstract


This paper deals with modeling and simulation of Solid State Circuit Breaker using MATLAB Simulink. The Solid State Circuit Breaker is developed using four power diodes and one Silicon Controlled Rectifier. The voltage across the load is sampled and is rectified to obtain the control signal. The closed loop system detects the fault and the Solid State Circuit Breaker is opened by inhibiting the pulses. The results of sustained fault condition and the closed loop condition are presented. The Solid State Circuit Breaker has advantages like arc free interruption and reduced hardware. The aim of this paper is to model and simulate the Solid State Circuit Breaker.
