Abstract:

Climate change is a global phenomenon which is becoming increasingly concerning. International efforts, such as the Paris Agreement [1] lead to transport electrification initiatives. HYPOBATT [2], in marine sector, aims for the charger that will enable a full electric vessel to be a reality. These systems have great amounts of energy storage. Together with electric machinery, EMI filters and distribution grids usually can sum up to some mF capacitance to earth, becoming a problem when detecting faults to ground, and therefore, a safety issue. To detect earthing faults insulation monitoring dev

Abstract:

A new model is proposed for analyzing the capacitive effects in a newly developed high frequency coaxial transformer (HFCT). The proposed model can describe both the electric energy storage and common-mode (CM) electromagnetic interference (EMI) noise behaviors of a transformer, considering the voltage distribution in the HFCT windings. To determine the parameters of the model, a parasitic capacitance network is developed to describe the HFCT’s real winding’s structure, and the distributed parasitic capacitances of the network are evaluated using FEM based on the theory of capacitances in a mu

Abstract:

A simple yet efficient approach is presented to extract the via-plane capacitances for an offset via structure. According to the integral approximation approach, the geometry of offset via is first divided into several segments with equally distributed angles from the origin. The two-dimensional FEM method for the concentric case is used for each segment based on its pad-stack parameters. Then, the final offset via-plane capacitance is approximated as the average of these ‘segmental’ capacitance values. Numerical examples demonstrated that the combined method has similar accuracy with a three-

Abstract:

The bandwidth of very high gain (≥100 MV/A) transimpedance amplifiers is restricted to below 100 kHz, unless measures are employed to mitigate the effect of circuit parasitic capacitances. Current approaches involve significantly increased circuit complexity and component count. They may suffer unwanted noise pickup or destructive capacitive coupling to ground, the latter restricting the available bandwidth. We demonstrate that combining a positive feedback circuit with a low-pass filter network extends the bandwidth of a transimpedance amplifier out to the limit of gain peaking (>1 MHz) wi

In deep-submicron technology, global interconnect capacitances have started reaching several orders of magnitude greater than the intrinsic capacitances of the CMOS gates. The dynamic power consumption of a CMOS gate driving a global wire is the sum of the power dissipated due to (dis)charging (i) the intrinsic capacitance of the gate, and (ii) the wire capacitance. The latter is referred to as on-chip signaling power consumption. In this paper, a scheme has been proposed for combating crosstalk noise and reducing power consumption while driving the global wire at an optimal delay. This scheme

Composite nanomaterials are made by oxidizing BC (Bacterial Cellulose) with TEMPO. The resulting TOBC (TEMPO Bacterial Cellulose) material was mixed with Ppy using the in situ method. The mixture is then drawn wet—measurement of current density and capacitance using Cy

Abstract:

A detection system of capacitive sensor is designed and the application of capacitive sensor in measurement of material transportation is discussed. On the basis of measuring the dielectric constant change of the material in conveyor, the system can detect density variation of the material. The signal conditioning circuit of measurement system consists of capacity/voltage conversion circuit, phase shifter and programmable gain amplifier etc. It can reduce the influence of cable’s distributed capacitance and other parasitic capacitance. The results show that the system has high measurement prec

Abstract:

In this study, the effects of hydrogenation on the dielectric capacitance and leakage current of ZrO2/Al2O3/ZrO2 (ZAZ) films for dynamic-random-access memory (DRAM) capacitors were examined. Hydrogen permeation into ZAZ films reduced the dielectric capacitance and increased the leakage current with continued exposure to hydrogen during the forming gas annealing process. More specifically, the hydrogen ions distributed in the grain boundaries and at the Z/A interfaces appeared to disrupt the dipole motion and diminish the dielectric constant of the film, resulting in a decreased dielectric capa

Abstract:

Nonpolarizable electrodes are applied widely in the electric field measurement for geophysical surveys. However, there are two major problems: (1) systematic errors caused by poor electrical contact in the high resistive terrains and (2) environmental damage associated with using nonpolarizable electrodes. A new alternative structure of capacitive electrode, which is capable of sensing surface potential through weak capacitive coupling, is presented to solve the above problems. A technique is introduced to neutralize distributed capacitance and input capacitance of the detection circuit. With

Abstract:

The Gas-insulated Line (GIL) is a technical equipment that allows power transmission underground at high voltage level. The UHV GIL-overhead hybrid transmission line is an essential way for power transmission in complicated landscapes. Because of the distributed capacitance of the UHV transmission line and the difference of the structure and the electrical parameters between GIL and overhead transmission line, the distance protection based on uniform lumped parameters cannot be applied to this hybrid transmission line directly. In order to overcome the shortcomings, this paper studies and prop

Abstract:

A binder-free process for the electrode preparation for supercapacitor application was suggested by drop casting graphene nanoplatelets on a carbon fiber (GnP@CF) followed by electrodeposition of Ni nanoparticles (NPs). The microstructure of the electrode showed that Ni was homogeneously distributed over the surface of the GnP@CF. XRD analysis confirmed the cubic structure of metallic Ni NPs. The Ni-GnP@CF electrode showed excellent pseudocapacitive behavior in alkaline solution by exhibiting a specific capacitance of 480 F/g at 1.0 A/g, while it was 375 F/g for Ni@CF.
