    Abstract: 本文旨在研製一以數位訊號處理器為控制核心之風力發
    This thesis presents the design and implementation of power
    converters for wind generator (WG) controlled by a digital signal
    processor. The system is composed of a wind generator, lead-acid
    batteries, a dc/dc boost converter and a bi-directional dc/dc
    converter. The wind generator is the main power source of the
    system, and the battery is used for energy storage and power
    compensation to recover the natural irregularity of the wind power.
    Since the output power of wind generator varies with the change
    of wind speed, the flexible control strategy is used to determine
    the system working state and the operating mode of bi-directional
    dc/dc converter. In charging mode, the battery is charged by
    multi-stage current charging method with maximum power point
    tracking (MPPT) algorithm to raise the charging efficiency and
    completely employ the finite power. Fuzzy logic control
    algorithm is used to improve the transient response when the
    battery discharges in discharging mode.
    This thesis adopts wind generator simulation systemas the
    power source. Finally, a 100 W power converter system is
    constructed and the performance is verified.
