Dual stator generator has excellent cogging torque characteristics and can generate a high voltage, thus minimizing the loss that occurs when boosting. Moreover, It has a high output ratio to the same volume because the voltage is generated from the inner and outer generator. Dual stator permanent magnet generator is operated in a single phase by connecting the inner and outer generators in series in order to secure high voltage, so it must be controlled in a different way from conventional three phase power conversion system. In this paper, we proposed a method of design and controlling a grid-connected power conversion system using a dual stater generator. The proposed method was verified through simulation.

Methods of speed control of single-phase inuction motor include pole change and frequency control. Pole change method that is controlling the speed by converting the number of poles of the motor using only simple pole change device has lower capability of speed control than method of frequency control. However pole change method is more economical than method of frequency control because it has low manufacturing cost. In this paper we propose a method of improving the operating capability of 2-pole/4-pole using pole change method different from conventional method and the operating capability for each number of poles applied with the winding arrangement method is verified through finite element analysis.
