Fault Identification and Mitigation in Seven Level Cascaded H Bridge Inverter for Vehicular Application
National efforts to improve air quality in heavily populated urban communities by reducing vehicular tailpipe emissions have rekindled interest in the development of electric vehicle technology and infrastructure. Electric vehicles make ideal urban commuter vehicles, for driving to and from. To fulfill increasing demand for higher dependability in power semiconductor converters applicable in electrical vehicles, fault detection (FD) and mitigation is a very important. During this study, a model based on open semiconductor switch fault and closed semiconductor switch fault designation methodology is conferred for a voltage source electrical inverter (VSI) supply a Squirrel Induction motor drive. To understand this goal, a model based designed by using simulink. After that, the model is studied with and while not of each open and short faults. Afterwards, the planned FD technique identifies the faults within the H bridge cell. The conferred FD technique is easy and fast; additionally, it's able to sight multiple open switch or open faults in distinction to standard ways. On the opposite aspect, so as to mitigate the occurred faults, the fault occurred switch leg of the cell has been shorted.
