Abstract—In this paper is designed and implemented a solar and wind turbine hybrid power generation system. That can be divided into the following parts, the wind turbine utilizes a three-phase switch-mode rectifier (SMR) while the solar power employs a DC/DC boost power converter together to improve the input power factor and minimize the input current harmonics distortion. This hybrid power generation system working with the perturb-and-observe algorithm Maximum Power Point Tracking (MPPT) strategy is capable of achieving robust optimum power output in working condition. Besides, to balance the DC bus and stabilize the output power, the battery system is adopted and incorporated in the hybrid system. The battery system uses a buck/boost dc chopper as the charge and discharge circuit. In the output stage, a single-phase full-bridge inverter employs the sinusoidal pulse width modulation (SPWM) strategy to generate a single-phase 60 Hz AC source to the load. The hybrid generation system is realized by using a digital signal processor (DSP) as a centralized controller to all the switching unit, and to verify the validity of the proposed architecture by recording the day-based power variation of the hybrid power system.
