Abstract :
The full bridge inverter is one of the power electronics converters that are widely used in a lot of systems like active filters, motor drives, uninterruptible power supplies, etc. However, its components used to fail mainly when they are operated in frequencies and voltages higher than the rated ones. To avoid damages in the load of the full bridge inverter it is important to apply a fault detection and isolation system in the fault transient stage. This paper shows the design and simulation results of the application of a hybrid bond graph diagnostic system to the full bridge inverter. This diagnostic system, that is a quantitative approach, is well suited for power converters and gives the possibility of obtaining diagnostic properties. The results of the investigation are presented by means of simulations and show that all of the fault considered can be detected and isolated.
