摘要: Fault-tolerant converters have been widely investigated for years and nowadays an extensive technical literature on this field exists. This paper presents a novel fault detection algorithm based simple geometrical approach. In the analysis both case of faults in single device lose entire inverter leg considered. False positive detections are avoided by considering proper number current samples. The proposed is characterized simplicity, low computational implementation effort with consequent enough fast execution, easy control integration possibility to use it hardware loop systems Microprocessor common industrial usage. verified simulation tools experimental results reveals valid suitable alternative actual state art detection.
