    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
    電機電源轉換器系統,系統由風力發電機、鉛酸電池、直流升
    壓轉換器與直流雙向轉換器建構而成。風力發電機為系統主要
    電力來源,電池則負責儲存能量與功率補償,以彌補風能先天
    上較為不穩定之特性。由於風力發電機之輸出功率易隨風速改
    變而有所變化,因此運用彈性控制策略以決定系統之運作狀
    態,調整直流雙向轉換器之操作模式。充電模式時,結合發電
    機最大功率追蹤控制與多階段定電流充電法對鉛酸電池充
    電,提升充電效率並充份利用有限之電力;放電模式時,則利
    用模糊邏輯法改善電池放電之暫態響應。本文採用風力發電機
    模擬系統作為系統電源,使系統輸出為一穩定之直流電壓
    (70V),並將負載消耗之功率維持於100W。
    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.
