Renewable Energy and Electrical Machines

In recent years, each country in the world has struggled against the global warming. Since wind is one of renewable resources of energy, we have proposed a novel wind power generator system. In May 2006 we introduced a 40-kW wind turbine generator system, which is of practical scale and is equipped with the power converter proposed in our laboratory, in TDU Chiba-Newtown campus.  Various performances of this system are being investigated for any wind conditions. Moreover, permanent magnet synchronous motor (PMSM) drive systems are one of our major research projects since PMSMs have many features such as high efficiency and long life. Also, our research interests include a shaft generator system used for electrical power sources in large ships, and parallel operation of uninterruptible power supply systems (UPSs) for computers.
