In the paper, firstly, the insulation aging and insulation cut or crack fault models of DC feeder cable were established; then according to the characteristics of electrical and loads of DC feeder cable, the Rail- Voltage law and different DC current law were purposed in the orbital theory, and the feasibility of purposed law were discussed from engineering view. The results of analysis show that...
An array of transfer length mode (TLM) structures were designed and made on electrically isolated phosphourous -doped hydrogenated amorphous silicon (a-Si:H) thin films. Annealing effects on NiCr/a-Si:H contacts in the temperature rang from 100 degC to 400degC were studied. Electrical measurements were performed to characterize the interaction of the contact between NiCr alloy and doped a-Si:H thin...
In this paper, the far field properties of the lossless metamaterial covered perfectly conductor and air cylinder are discussed. The model configuration is given. Under different geometrical and electromagnetic parameters, the far field properties of the model are investigated through the directivities and normalized radiation resistances. Important regularity is obtained.
DSM and nanometer VLSI designs are subject to an increasingly significant thermal effect on VLSI circuit lifetime and performance variation, which can be effectively subdued by VLSI placement. We propose analytical placement for accurate and efficient VLSI thermal optimization, and propose minimized maximum on-chip temperature as the thermal optimization objective for improved VLSI lifetime and minimized...
An area of interest for dynamic voltage restorer (DVR) research is the damping of transient oscillations initiated at the start and at the recovery instant from a voltage sag. Nonlinear loads, with harmonic currents close to the DVR filter resonance frequency, can also excite the resonance oscillations. To compensate voltage sags and dampen high-frequency oscillations simultaneously, an investigation...
