Power electronic systems could be unstable due to the interaction between converters. Impedance-based stability analysis is an effective approach to predict stability and to provide design criteria. Therefore significant are impedance measurement techniques, which have been well established for DC systems, but need to be improved for AC systems nevertheless. This paper proposes a novel AC impedance...
The recognition of human motions based on wireless sensor network technology has several obvious advantages. Since traditional recognition technology adopts a single wireless link, it is effective to identify whether an individual stays in a certain area. However, the technology fails to effectively recognize high-level human motions such as falling and lying down, which is of great importance for...
The conventional droop control method, which does not require communication lines, is an effective control scheme to dispatch power among inverters in the microgrid. However, this method has inherent tradeoffs: frequency vs. active power accuracy and amplitude regulation vs. reactive power sharing accuracy. To cope with this problem, this paper presents a novel active power control strategy to improve...
Cascaded H-bridge (CHB) multilevel inverter has gained more and more focus due to its adaptability to high-power, high-voltage applications and capability of fault tolerant. In this paper, modeling of the CHB multilevel inverter under RMS feedback control is presented. This particular control scheme is suitable for the control system that has a strong demand for the output voltage amplitude accuracy...
