- Resumen
Wind power generation has become one of the most important energy sources. Currently, due to the advances achieved in power electronics and vertical-axis small wind-turbines, the urban integration of wind-energy has increased considerably. In this work, three three-phase rectifiers are proposed to inject the energy from a permanent magnet synchronous generator to a microgrid DC-bus. By means of sliding mode control these architectures are modeled as a three-phase Loss Free Resistor allowing the power factor correction in each phase and obtaining a modular and redundant implementation. However, due to the cost of the microgrids implementation, a boost inverter is proposed to obtain the most basic configuration for grid-connection. Using the boost inverter a sinusoidal output waveform can be obtained for input voltages lower than mains voltage. Finally, the DC voltage and the DC-link capacitor can be adjusted in order to optimize the global efficiency.
