This paper deals with a dual active bridge (DAB) converter based battery charger in a stand-alone wind power generation system with a high-inertia small-scale wind turbine. The conventional proposed system needs four converters from a generator to the motor load. This proposed system can improve power conversion efficiency by reducing the number of converters. The DAB converter performs as battery controller. When the generated power is larger than the consumed power of the motor load, the DAB converter acts battery charging mode. On the other hand, when the generated power is smaller than consumed power of the motor load, the DAB converter acts battery discharging mode. Simulation results demonstrate that the proposed system can control the power flow in the stand-alone wind power generation system.
