An analytic expression describing the complex voltage measured between the pickup points of a four-point probe, in contact with the surface of a half-space conductor, is derived. The driving current is assumed to be time harmonic. There are two contributions to the measured voltage. One arises from the potential drop due to electric current flowing in the conductor. The other arises from induct...
As semiconductor manufacturing technology advances, power dissipation and noise in scan testing has become a critical problem. In our studies on practical LSI manufacturing, we have found that power supply voltage drops cause testing problems during shift operations in scan testing and we have analyzed this phenomenon and its causes. In this paper, we present a new testing method named MD-SCAN ...
In this paper, a new droop-based reactive power control strategy is proposed that is suitable for implementation in autonomous low voltage microgrids. The proposed method exploits the potentials of adding a dynamic virtual inductance loop to compensate for the voltage drop differences caused by line impedances. In addition, it provides a large virtual inductance at the output terminals of a dis...
Variations in the switching threshold voltage of memristive devices present significant challenges for their integration into large-scale circuits. In this paper, we propose to address this problem by adding a device exhibiting S-type (N-type) negative differential resistance (NDR) in series (parallel) with memristive devices. The main effect comes from the transition between lowand highconduct...
This work study voltage correction using capacitor banks on PLN’s network distribution with medium consumer of PT. Panca Agung Sejati. Voltage drop into Sejati in operation condition is 17.87 kV, it mean happened persentage 10.65. That not apropriate to the SPLN 72:1987 standard, that is+ 5%. While, company still range standard when by 19.67 kV (1.65%). Then, efforting improve PLN (Persero) has...
In this paper we model and experimentally verify the evolution of liquid water and nitrogen fronts along the length of the anode channel in a Proton Exchange Membrane Fuel Cell operating with a dead-ended anode that is fed by dry hydrogen. The accumulation of inert nitrogen and liquid water in the anode causes a voltage drop, which is recoverable by purging the anode. Experiments were designed ...
In this paper, we first report a micropump actuated by surface tension based on continuous electrowetting (CEW). We have used the surface-tension-induced motion of a mercury drop in a microchannel filled with an electrolyte as actuation energy for the micropump. This allows low voltage operation as well as low-power consumption. The micropump is composed of a stack of three wafers bonded togeth...
This paper presents logic level estimators of leakage current for nanoscale digital standard cell circuits. Here the proposed estimation model is based on the characterization of internal node voltages of cells and the characterization of leakage current in a single Field-Effect Transistor (FET). Finally the estimation model allowed direct implementation of supply voltage variation impact on le...
This paper investigates the influence of the power converter on the performance of Surface Mounted Permanent Magnet Synchronous Motor Drives, which employ High Frequency Voltage Injection to achieve low speed control. The effects of IGBT voltage drop, deadtime and deadtime compensation on position estimation are discussed and the use of Matrix Converter is proposed to reduce these effects. Spac...
We have studied the resistance of single-wall carbon nanotubes measured in a four-point configuration with noninvasive voltage electrodes. The voltage drop is detected using multiwalled carbon nanotubes while the current is injected through nanofabricated Au electrodes. The resistance at room temperature is shown to be linear with the length as expected for a classical resistor. This changes at...
