| Abstract | This work presents a DC-DC boost converter, controlled to track the point of maximum power (MPPT Maximum Power Point Tracking) of a small electrical generation system (less than 5kW). The converter uses the intrinsic inductance of rotating electrical machines, does not require the use of sensors such as speed and position and its small weight and volume contribute to the reduction of cost, if it become a product to market. In the first part of this work is presented a study about a permanent magnet synchronous generator of axial flux, which has advantages in that it concerns the power to weight ratio and generation at low speed. Then, the characteristics of the converter and its control system are presented, based on an analog circuit, and simulations are conducted to demonstrate the efficiency of the converter with MPPT. The confection of the prototype is presented detailing the choice of components and assembly. Finally, we present the experimental results, which confirm the expected results, and conclusions about all the work. |
