The extension of capacitive behavior to the AC regime (∼100 Hz) opens up an avenue for a number of new applications where physical volume of the capacitor may be significantly reduced. | |
Thus, the capacitor deterioration can be diagnosed. | |
The ICS is unaffected by the environment and can provide direct measurement of real-time fan operational status by sensing the AC current drawn by the fan motor. | |
The chemistry developed during this study displayed long-term cycling potential and demonstrated the stability of the capacitor for continued usage. | |
32 Citations | A standard method for testing fan cooling effect and an index for determining fan efficiency, such as the CFE index proposed in this study, need to be developed. |
The research reported in this paper indicates that the filter capacitor will accumulate and dissipate increased amount of charge when the rectifier is subjected to ac source voltage fluctuations. | |
41 Citations | This paper presents a new measuring method for comparing different impedances, which allows, for example, the capacitance and the dissipation factor of a capacitor to be determined from the resistance and the time constant of an AC resistor. |
The analysis of experimental results indicated that longitudinal and fan-shaped non-uniform pollutions compared to uniform pollution contributed to an increase and a decrease in the ac flashover voltage, respectively. | |
On the basis of collected fan-use models, probit regression models of fan-use rates and ambient environments were obtained and indicate that the essential trigger of fan-use is a warm environment rather than building types. | |
5 Citations | Due to the elimination of the fan power in the proposed method, the efficiency of the dc–dc converter increases during the hold-up time; thus, the energy stored in the link capacitor decreases less sharply, compared with the conventional method. |
