The system utilizes the finite element method as well as various modules to achieve a real-time effect in the analysis of electrical machines while hands-on experimentation is in progress. The proposed system is aimed at developing a tool that would help improve the student's understanding of electromagnetic fields inside these machines and its use in calculating performance measures as well as operational concepts pertaining to the practical study of electrical machines

The renewable energy sources under study include a photovoltaic (PV) source and a wind energy conversion system (WECS). The PV source yields a variable DC output voltage that is dependent on the solar irradiation and ambient temperature. Therefore, a power conditioning unit (PCU) is needed to integrate its energy to the power system and track its maximum power point (MPP). The power conditioning unit may be a controlled DC-DC boost conveter. The design and implementation of such converter is investigated in the paper. Moreover, wind generators yield an AC output voltage that has variable voltage magnitude and frequency. Hence, a complete WECS has to be developed to integrate this wind energy to the power system. The WECS involves an uncontrolled (diode) rectifier cascaded by a controlled DC-DC converter. Furthermore, the renewable energy system involves a battery storage system that in turns need a converter to control its charging/discharging process. The design and control of this converter will be presented in this paper as well. Simulation and experimental results are included to verify the ideas developed in this study.
