Tail bits in the RESET process influence the distribution of resistive parameters, and will dramatically decrease the uniformity in high electric stimuli region. In this study, such phenomena can be explained as non-uniform distribution of defects in the insulating layer and high defects density in the bottleneck region of conductive filament (CF). Then departing from defects' distribution function,...
A passivity-based robust control via second-order sliding mode for a class of input-affine nonlinear systems is presented in this paper. The proposed approach consists of: 1) a feedback control term that makes the closed-loop system passive w.r.t. an additional control input as well as 2) a robust control term using a second-order sliding mode approach to counteract the influence of system parameter...
The Roll-Ring with a rolling electrical contact is usually utilized in an electrical energy transmission system between two continuous relative rotated equipments, such as the rotation system in radar, tank, space station and so on. As long as the requirement of the transmission power increasing in these years, the rolling electrical characteristic is more and more important for the long-life design...
Within this paper, the arc characteristics in a typical air DC circuit breaker (DCCB) are studied through experimental approach. A specially designed experimental setup is employed to observe the dynamic process of arc evolution. The phenomena of arc commutation and arc stagnation under fault currents are revealed according to the high-speed photography and arc voltage curves. The influence of arc...
This study designs and fabricates a novel suspending micro-switch on silicon substrate using surface micromachining techniques for wireless communication. The proposed Si-based micro-switch with dimensions of 750 µm × 850 µm × 500 µm is constructed of one bottom GSG electrode, four non-isometric springs and two arched top electrodes. Using commercial Ansoft-HFSS simulation software, the dimension...
