12 Citations | Overall, the results reveal that the AC composite electrodes with 40 wt% LiFePO 4 loading on a Na 2 SO 3 neutral electrolyte exhibit high cycling stability and reversibility and thus display great potential for electrochemical capacitor applications. |
Such behavior of ln( σ ac ) vs ln( ω ) plot indicated that there are two different conduction mechanisms in the Au/GO-doped PrBaCoO nanoceramic/n-Si capacitor at room temperature. | |
The accuracy of physical parameters of a tunable MEMS capacitor, as the major part of MEMS AC voltage reference, is of great importance to achieve an accurate output voltage free of the malfunctioning noise and disturbance. | |
By using of the proposed and described estimation-correction solution the impedance measurement error can be decreased from several tens of ohms till few ohms or even less, if using the fixed 1 kOhm resistor /Zx (measured impedance) voltage divider for the measurement circuit. | |
On the basis of an experimental approach, it is shown that an accurate equivalent circuit must include a capacitor. | |
The results show an ideal capacitor nature with a significant energy density value. | |
The accuracy of the manufacturing parameters of tunable MEMS capacitor as the main element of the MEMS AC voltage reference is of great significance to obtain a precise output voltage. | |
01 Oct 2018 | The method can be further extended for electrolytic capacitor on-assembly testing. |
61 Citations | After prolonged floating of the AC/AC capacitor at 1.6 V and −40°C, the capacitance, equivalent series resistance and efficiency remain constant, demonstrating the absence of ageing related with side redox reactions at this temperature. |
71 Citations | The technique of ac impedance combined with equivalent circuit clearly showed that oxidized CNT/CP capacitor imparts not only enhanced capacitance but also a low equivalent series resistance. |
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. | |
24 Apr 2006 40 Citations | Therefore, the behavior of an electrolytic capacitor varies from approximately a simple capacitor for low frequencies, to a resistor at its resonance frequency, and finally to an inductor for frequencies higher than its resonance frequency. |
So if the capacitor is used in ac or pulsed applications, electrochemical corrosion will occur in the aluminum electrode. | |
These results can contribute to improving understanding of and optimizing performance of asymmetric Ni(OH) 2 –AC capacitor. | |
Therefore, PDHA/AC composite electrodes were more promising for application in capacitor. |
