Electrical power is one of the factors that most influences the economic development of our society. Since the beginning of the use of electricity the continuous improvement of generation, distribution and use of electricity tries to satisfy the ever increasing quality and performance needs of most sectors of human activity. The power quality of the electrical network is mainly related to the t...

This paper proposes an alternative configuration for digitally controlled parallel connected DC–DC power converters. Unlike conventional scheme which uses only one digital controller to control all of the n parallel connected power converters, the proposed scheme employs n digital controllers for n paralleled power converters. This arrangement prevents single controller breakdown from faulting ...

The paper presents soft switching PWM DC-DC converters using power MOSFETs and IGBTs. The attention is focused mainly on the full-bridge converters suitable for high power applications. The properties of the PWM converters are described in comparison to other categories of soft switching converters. An overview of the switching techniques using in the DC-DC converters is included. Consideration...

In CRUTIAL, the deployed testbeds are composed of two platforms. The first platform is based on power electronic converters that are controlled from PCs that are interconnected over an open communication network (at K.U.Leuven). The second platform consists of power station controllers on a real-time control network, interconnected to corporate and control centre networks (at CESI RICERCA). Thi...

Wind Energy Generation Systems (WECS) are confronted with increasing demands for power quality and harmonic distortion control. With the advances in power electronics technology, the rapid growth of variable speed WECS is now witnessed. However, the power quality still remains an important issue to be addressed thoroughly by researchers. This paper presents a comparative study on grid connected...

Dynamic voltage and frequency scaling (DVFS) is a powerful technique to reduce power consumption in a chip multiprocessor (CMP). To support DVFS in the multicore power delivery network, we integrate on-chip switched-capacitor (SC) DC-DC converters that can work with multiple conversion ratios to provide varying levels of Vdd supplies. We study the application of such SC converters in multicore ...

In this paper, a complete computer aided procedure based on the power density concept and aimed at the automatic design of EMI filters for power electronic converters is presented. It is rule-based, and it uses suitable databases built-up by considering information on passive components available from commercial datasheets. The power density constraint is taken into consideration by imposing th...
