Abstract

Fault Diagnosis in a DC-DC converter is very important to prevent the converter from the damage. The aim of the paper is to diagnosis the fault and to prevent the converter from the damage. This Paper deals with design, modeling and simulation of open and short circuit switch fault analysis using MAT Lab Simulink. The converter used here is a Positive Output elementary Super Lift LUO Converter (POESLLC). Open Circuit and Short Circuit Switch faults are created, and cleared using a closed loop control and corresponding waveforms are studied. The Simulation results are compared with theoretical results. A simulink model is developed and it is successfully used for fault diagnosis.
