The asynchronous systems are the models of the asynchronous circuits from the digital electrical engineering. An asynchronous system f is a multi-valued function that assigns to each admissible input u : R → {0, 1}m a set f(u) of possible states x ∈ f(u), x : R → {0, 1}n. A special case of asynchronous system consists in the existence of a Boolean function Υ : {0, 1}n × {0, 1}m → {0, 1}n such t...

This paper presents the design of a restartable crystal controlled clock. The clock generator is a critical component in a newly proposed blended design methodology which combines clockless and clocked subsystems and is a special case of a Globally Asynchronous Locally Synchronous (GALS) design strategy. The clock generator has been successfully implemented in the TSMC 0.25μm NWELL process, occ...

In this paper a variable speed generating unit is considered, equipped with permanent magnet generator. The system analysis involves appropriate models for the generator, the static converter and the grid. Moreover, an asynchronous generator mounted on the same rotor with dump loads ensures braking actions and management of the active power produced. The modelling of the generator and power ele...

The asynchronous systems are the non-deterministic models of the asynchronous circuits from the digital electrical engineering, where non-determinism is a consequence of the fact that modelling is made in the presence of unknown and variable parameters. Such a system is a multi-valued function f that assigns to an (admissible) input u : R! f0; 1gm a set f(u) of (possible) states x : R! f0; 1gn:...

The need to decentralize power generation and decarbonize the earth in order have a sustainable global economy are major reasons for development of this paper. Considering flaws grid-connected system, autonomous system becomes better alternative rural isolated areas. Analysis stand-alone single-phase Asynchronous generator based on d-q model stationary reference frame is presented. does not cap...

This paper presents generic model of hybrid power system consisting in a combined solution one wind turbine with asynchronous generator and on hydro generator with synchronous machine. This technology was developed by to reduce the cost of supplying electricity in remote communities. The optimal wind penetration (installed wind capacity/peak electrical demand) for this system depends on the sit...
