Design and Implementation of Power Converter for Low Power Windmill

With the unpredicted development in industrial growth the need for electricity is increasing day by day. To meet the power demand we are going for non-conventional energy resources. The wind sources are not constant hence we are applying the MPPT algorithm in embedded controllers and boost/buck the voltage based on the available source of input. These sources can be boost and given to the voltage source inverter and inject the generated voltage to the grid. Hence the power demand can be reduced by this method. Now a day¿s microcontroller-based control in power converters has become an intensive area of research due to its features of simple circuitry, software control and flexibility to adapt to various applications. However, PWM generation and current control loop require a high sampling rate to achieve wide bandwidth performance. Therefore, most computational resources of the controller must be utilized for PWM gating signal generation and the execution of current control loop algorithms. Only a limited time is left to control other functions of the drive.
