In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...

The current study empirically demonstrates the widely discussed gap between copyright law and social norms. Theoretically founded in the sociology of law, the study uses a well-defined concept of norms to quantitatively measure changes in the strength of social norms before and after the implementation of legislation. The ‘IPRED law’ was implemented in Sweden on 1 April 2009, as a result of the...

This paper describes the various software modules of the International Collaborative Environment (ICE), a system implemented as a collection of components written in Java. The system allows groups to collaborate, both synchronously and asynchronously, and perform a variety of tasks over the Internet. The components, all of which are shared by users in the same group, include chat, whiteboard, e...

the aim of current research is to determine how factors of job attitude, subjective norms regarding knowledge sharing, and perceived behavioral controls affect knowledge sharing behavior, considering the role of organizational citizenship behavior as a mediating factor. to achieve this purpose, the research data was collected by providing research questionnaire in 384 members of the hospital st...

as one of the most important components of a nations basic facilities, the networking of the library plays a vital role in terms of promoting the sharing of access to information. although the traditional methods of literature indexing and accessing will continue to exist and develop, library networking will become the new model and the direction for the development of the library. through the ...

An accurate, wide output swing, low voltage charge pump is proposed. It is based on a second generation current conveyor which is used to equate charging and discharging currents. A low voltage enhanced current mirror ensures matching between nominal and output currents and current steering is used to minimize charge sharing. Simulation results characterize performance of the proposed circuit.

the purpose of this research is to predict knowledge sharing through dimensions of social capital. knowledge sharing occurrence depends directly upon tendency of knowledge holder to sharing as well as knowledge receiver to take it from holders. in other side, social capital is defined as linkage among people and their unifying factors such as trust. in this research, social capital is conceptua...

Parallel connection of inverter modules is a solution to increase reliability, efficiency and redundancy of inverters in Micro-Grid system. Proper load sharing among parallel inverters is a key point. The circulating current among the inverters can greatly reduce the efficiency or even cause instability of the system. In this paper, a control strategy for improving the load sharing performance ...
