Improving efficiency of electrical machine is of paramount importance to optimization of operational and resource management. Efficiency method which do not account for iron loss could undermine the effective efficiency estimation. This paper simulates the efficiency variations of electric machine in both transient and steady state, magnetic flux linkages are used instead of the traditional cur...
This article proposes a double-synchronous-reference-frame-based power-synchronized grid-following inverter (DS-PSGFLI). In contrast to existing types of phase-locked-loop (PLL)-based inverters (GFLIs) and PLL-less GFLIs (PSGFLIs), the suggested DS-PSGFLI operates seamlessly during unbalanced grid faults in both strong weak connections, while maintaining stability avoiding oscillations. Further...
A new method for imaging high frequency plasma fluctuations is described. A phase locked loop and field programmable gate array are used to generate gating triggers for an intensified CCD camera. A reference signal from another diagnostic such as a magnetic probe ensures that the triggers are synchronous with the fluctuation being imaged. The synchronous imaging technique allows effective frame...
This paper proposed a control method for output and circulating currents of modular multilevel converter (MMC). The current are controlled with the help arm currents, which contain DC, fundamental frequency, double frequency components. is transformed into stationary reference frame (SRF) to isolate DC AC component conventional proportional resonant (PR) controller, while by controller. effecti...
Genome-scale expression data on the absolute numbers of gene isoforms offers essential clues in cellular functions and biological processes. Smooth muscle cells (SMCs) perform a unique contractile function through expression of specific genes controlled by serum response factor (SRF), a transcription factor that binds to DNA sites known as the CArG boxes. To identify SRF-regulated genes specifi...
