A new CMOS buffer without short-circuit power consumption is proposed. In this work, the gate-driving signal of the output pull-up (pull-down) transistor is fed back to the output pull-down (pull-up) transistor to get tri-state output momentarily, eliminating the short-circuit power consumption. The TSPICE simulations are used to verify the operation of the buffer. It is observed that the power...

Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

The optics of axial silicon nanowire solar cells is investigated and compared to silicon thin-film solar cells with textured contact layers. The quantum efficiency and short circuit current density are calculated taking a device geometry into account, which can be fabricated by using standard semiconductor processing. The solar cells with textured absorber and textured contact layers provide a ...

I certify that the engineering design of the new vehicle described in this report, Johnny-5, has been significant, and that each team member has earned six semester hours of senior design credit for their work on this project.

As researchers, one of our common goals is to expand our reach and our capabilities as human beings through the development of new technologies and new ideas. Often we use immense resources to explore this new territory. However, an unfortunate side effect of this essential activity is that the number of individuals that can participate in this search becomes smaller and smaller as the resource...

To one double-breaker model, experimental investigation on blow open force was carried out. It demonstrates that the ratio between the emerging blow open force and arc power FB/ui decreases with the arcing time, the contact gap has less effect on FB/ui, and the characteristics of the blow open force are similar when the peak value of the short circuit current is beyond 4 kA. Then, according to ...

This paper deals with the most relevant issues about the integration of renewable generation in weak power grids. Initially, the main parameters that characterize these types of networks are reviewed, in terms of short circuit power, system inertia and frequency and voltage characteristics. Afterwards, improvement measures in the structure of weak power grids are proposed, analyzing different s...

Integration of wind turbine based on doubly fed induction generator (DFIG) into the electrical grid has become an important part of electrical generation in many countries and its importance is continuing to increase. A few of them are various speed generations, the decoupled control of active and reactive power and high power capacity. The current and future wind power situation is modeled as ...
