This study provides a comprehensive analysis of five-level cascaded H-bridge multilevel inverters (MLIs) under both normal and defective conditions. The paper outlines a fault-detection method that utilizes total harmonic distortion and a normalized output voltage factor.
For example, in wind turbines, inverter failure rates vary between the onshore and offshore architecture at rates of 27% and 8%, respectively. Additionally, for the solar photovoltaic sector, about 28% of the failures represent inverter faults .
There are numerous factors that contribute to these faults; among them are the overheating of the power switches caused by overloading and control failure, as well as external causes such as mechanical accidents and the impacts on the overall structure of the inverter.
Power inverter IGBT fault diagnosis IGBT's are widely used as a power inverter in several high-power applications. It is anticipated from Ref. that the occurrence of a fault in power switching devices will be 38 %. Almost all power inverters and IGBTs are used as switching devices due to their characteristics.
Reliability is a crucial factor to consider for multi-level inverters (MLIs) used in industrial applications. With the increasing number of power semiconductor devices, the potential for defects to significantly degrade the overall system is heightened. A highly effective fault-detection technique is required to minimize the impact of faults.
Researchers suggest new ways of inverter fault diagnosis like FFT and evolutionary neural networks , root cause analysis for sensor faults, experimental validation of the fault models, as well as real-time fault detection strategies without extra sensors for multilevel converters .
