A new open-circuit fault diagnosis scheme, which is capable for detecting one or two open-circuit fault of power switches in the back-to-back converter of a DFIG wind power generation system is proposed. A redundant topology for the back-to-back converter is set out enabling reconfiguration of the converter circuit once the faulty device or devices is(More)
Saliency detection has a great significance in improving image analysis and processing techniques. In this paper, we propose a center-focus global contrast saliency detection method. First, we achieve the weight of focus-center feature map from frequency domain and get the salient center by weighted coordinates; Secondly we calculate the Euclidean distance(More)
