In this paper several fault tolerant strategies which can be implemented on nine switch inverter has been investigated. The developed strategies provide compensation for open circuit and short circuit failures on semiconductor devices. In addition unique post fault controls have been proposed for each strategy. The first applied topology is switch redundant topology and can tolerate all switch failures...
Because of its great interest, the power systems reliability has been widely investigated in military, industrial and space applications. This paper is presenting an improved fault-tolerant inverter topology with its associated control strategy. This topology has been designed for aerospace industry that puts hard constraints on system reactivity and testability. In addition to the nominal and faulty...
This paper proposes a new robust fast power switch fault detection and compensation for a three phase shunt active filter without redundant leg. The approach introduced in this paper minimizes the time interval between the fault occurrences and its diagnosis. This paper demonstrates the possibility to detect a faulty switch of the active filter in less than 10 mus by using simultaneously a ldquotime...
The reliability of the VSI (Voltage Source Inverter) components such as semi-conductor switches is critical for the shunt active power filters. A failure in one of the switches decreases system performances and usually leads to disconnect the filter. So, to prevent such undesirable events, real-time fault detection, isolation and compensation must be implemented. This paper proposes new robust fast...
This paper studies 3 fault tolerant shunt three phase active filter topologies. It mainly details converter reconfiguration and uses an optimised fast and reliable fault diagnosis method, avoiding spurious semiconductor fault detection due to semiconductor switching. The fault tolerant converter topologies are based on classical three-leg active power filter topology but includes bi-directional switches...
