碩士 === 明新科技大學 === 電機工程研究所 === 97 === This thesis presents the design and implementation of an FPGA-based maximum-power-point-tracking (MPPT) charger for 400W vertical-axis wind-turbine generators. Because the maximum power point is not the same under the different wind speeds, the authors use the mixing of the perturbation and observation algorithm and the linear approximation method to get the maximum output power of the wind turbine generation system. The simulation system of wind-turbine generation is built in PSIM and used to analyse the converter and MPPT system operation. The digital control circuit has been designed using VHDL hardware description language. The simulation models for the MPPT controller have also been constructed and verified by using Simulink, PSIM and ModelSim cosimulation tools. The designed control circuit has been implemented on an Altera Cyclone FPGA logic device. Simulation and experimental results are shown to verify the viability of the proposed wind energy conversion system.
