本文旨在研發串聯式油電混合車之發電機控制系統。引擎運轉時可提供牽引馬達之能量，再經由功率轉換器可對蓄電池充電或提供負載所需之能量。文中含有新型交流-直流功率轉換器，其主要目的為控制發電機側之電流至直流負載。此新型交流-直流功率轉換器可依據發電機轉速判斷發電機應為 接線或獨立接線，以避免發電機之交流側端電壓大於直流電壓，提高發電機電壓使用率。本文系統亦包含三臂型直流-直流功率轉換器，配合蓄電池充放電控制使得發電機側之能量可對蓄電池充電或擷取蓄電池之能量供給直流負載。
本文以數位信號處理器(TMS320 F2812)作為控制核心完成實體製作。系統之發電機控制、蓄電池充放電控制及能量管理策略皆由C語言撰寫程式完成，引擎油門控制則由邏輯控制完成。最後完成360 W之引擎與蓄電池實體供電系統，並以實驗數據驗證系統之可行性。

This thesis is concerned with the development of the control system for series hybrid electric vehicles. The engine can supply energy to the generator and dc load as well as battery through power converter. A novel ac-dc converter is designed to control the current of the generator. The proposed ac-dc converter also decides the winding connection for generator in accordance with the generator speed to avoid excessive voltage on the ac side, and raise the voltage utilization factor of generator. A three-leg dc-dc power converter is introduced for the charging and discharging of battery and current sharing.

In this thesis, the digital signal processor, TMS320F2812, is used as the control core. C-language is used for generator control, battery charging and discharging, as well as energy management. A prototype of 360 W hybrid power converter system is built. Experiments are given to evaluate the proposed system performance.
