A widely-tunable and power-scalable clock generator for ultra-low power (ULP) applications is presented. Benefitting from a novel self-adjustable loop frequency response, the proposed phase-locked loop based clock generator exhibits a tuning range of three ...
Flexible AC Transmission Systems (FACTS) are systems based on power electronics using GTO or IGCT semiconductors [1] that allow a better use of the transfer capacities of the transmission lines and permit to satisfy the requirements due to the liberalizati ...
The principle of air compression can be utilized for the storage of electrical energy, with variable properties from the point of view of the energy efficiency. For the involved thermodynamic phenomena different approaches and realized systems lead to more ...
Dynamic power management is a design methodology aiming at controlling performance and power levels of digital circuits and systems, with the goal of extending the autonomous operation time of battery-powered systems, providing graceful performance degrada ...
In modern VLSI circuits, a large number of clock buffers are inserted in clock distribution networks, which are significantly affected by process and power supply noise variations. The combined effect of process variations and power supply noise on clock s ...
Power Factor Corrected rectifiers are a new tendency in development of power supplies. In the last few years, a lot of R&D activities have led to a new category of products for one phase applications. In this comtribuction, a new simplified topology is pro ...
Power Factor Corrected rectifiers are new tendency in development of power supplies. The present paper proposes a new simplified topology for three-phase applications, with only two active switches and able to generate symetrical currents in the line. Powe ...
