Summary:The reliability of the converter system is often reduced by power switch failures. Therefore, converter systems currently need fast switch fault detection and precise switch identification. The approach for the fault detection method for a boost converter based on fuzzy logic, suffering an open-circuit switch fault. The suggested fault detection technique considers the converter behavior investigation, especially the input current slope, when operating in both healthy and faulty states. Moreover, the fuzzy controller is applied to boost converter, which is supplied by a renewable energy source. The simulated results are presented in order to demonstrate the reliability of the suggested fault detection technique under various scenarios.
