Fault Identification Technique For Fault-Tolerant Boost Rectifier Based on SPMC Using Simulink/MATLAB

This paper presents an operation of the simulation model designed for fault identification within the proposed boost rectifier based on single-phase matrix converter (SPMC). The main goal of the fault identification technique is to locate a faulty switch during an open circuit fault (OCF) by observing the output voltage, the cycle of input supply and magnitude of inductor current. This is done by generating a binary code that acts as a signal for a controller to activate the relevant Current Option Route (COR) strategy-a setup meant to redirect current to working switches when a OCF occurs, ensuring the required current pathway in the circuit. The switching operation of COR strategy and fault identification technique is presented using Simulink MATLAB.
