Today, among the various renewable energy sources, wind power is the primarily acknowledged and confirmed its cost effectiveness. Globally, wind power utilization is increasing at noticeable rate. Continuously the technology is enhancing in order to obtain more power output from wind turbines. As the wind power output is proportional to the swept area of wind turbine, the rotor size is increasing continuously with grown-up capabilities of engineering and technology. On the other side, increasing rotor size generates some problems. To solve these problems, we proposed a multi-rotor wind turbine system also offer the advantage of standardization, transportation and ease of installation and maintenance. In this we are using three turbines with wind blades, three dynamos constricted with parallel. The wind energy obtained is stored to a battery through charging circuit. The battery supply is fed to pulse generator and in turn to a MOSFET which is capable of generating ON/OFF pulses of different frequencies. This is fed to a step-up transformer to generate a low voltage AC. This AC is fed as to the load.
