Nowadays multilevel converters have progressed in high power and renewable energy applications, because of their ability to generate multiple voltage levels. But the balancing of capacitor voltage, the existing of multiple DC sources and particularly protection issues in renewable energy application are the main problems of these multilevel converters. The proposed inverter in this paper, by mo...
The paper recommends polar voltage space vectors of the six-phase and two-level inverter as a useful mathematical tool for vector control inverter. model is described using three tools: analytic expressions, state, vectors. formulas allow determination elementary physical quantities: current voltage. state make it easy to define phase distribution in every possible are most important used inver...
This paper presents a real-time OS based on μITRON using proposed voltage scheduling algorithm for variable voltage processors which can vary supply voltage dynamically. The proposed voltage scheduling algorithms assign voltage level for each task dynamically in order to minimize energy consumption under timing constraints. Using the presented real-time OS, running tasks with low supply voltage...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
