| Summary: | 碩士 === 明新科技大學 === 電機工程研究所 === 99 === This thesis presents the design and implementation of an design and implementation of a maximum-power-point-tracking (MPPT) charger for traffic vehicles equipped with vertical-axis-wind-turbine generators. The charger is connected to a 36V battery to supply power to a DC load and equipped the vertical-axis-wind-turbine generators on the traffic vehicles. The system uses the perturbation and observation algorithm to get the maximum output power of the wind turbine generation system and use the small signal equivalent modeling to design voltage controller and to reach the input voltage control. The K-factor method is employed for the controller design to reach a better gain margin and phase margin.
In order to reduce cost, we constructed current sensor by low price components to replace the Hall sensor.
The system has been be realized by digital control method with VHDL hardware description language. The simulation models for the MPPT control have also been constructed and verified by using PSIM, Simulink 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.
