近年來全球暖化的危機浮現及油價飆漲情況下使得環保議題受到矚目，目前全球主要仰賴於石化能源，然而，根據世界能源會(WEC)的估計，世界的石油將於40-50年內用盡，因此搭載兩種動力源的複合式動力車，無疑成為近年來車壇的當紅話題。傳統內燃機雖然排氣污染較嚴重，但結合內燃機之優點與電動馬達的特性之複合式動力車輛(HEV)是目前省能且低污染具環保概念車輛的主流。
基於複合動力車輛的重要性並考量較大輸出扭力的需求，所以需要萬瓦級以上之大功率直流無刷馬達及大功率馬達驅動器，作為複合動力車輛之電能動力來源。雖然低功率馬達驅動器已經具備完整的研究，但是對於萬瓦級以上之高功率馬達驅動器的研究與設計仍然極少，高功率馬達驅動器比一般驅動器的設計、製作與工作穩定度更為複雜困難。因此，本論文根據此需求，研製2萬瓦特大功率永磁式直流無刷馬達驅動器，並應用於新型複合動力車輛平台，以滿足複合式動力車輛之大功率需求與驅動系統的可靠度。
本論文不但研究高功率直流無刷馬達驅動器設計且建構新型複合動力系統平台，來進行功能驗證及測試2萬瓦特直流無刷馬達在各種負載狀況下運轉之穩定性，並藉由實驗平台系統測試高功率2萬瓦特直流無刷馬達與內燃機之複合雙動力整合的功效並使系統能達到節能的效果。

In recent years, as the environmental protection and global warming has risen, it is important to reduce the pollution of environment. According to The World Energy Council (WEC) estimation, the petroleum of world will be use up in 40-50 year. A solution way is necessary to develop not the sole internal combustion engine (ICE) of compound vehicle. Thus, hybrid electric vehicles (HEVs) are recognized as one of the most promising technologies in significantly reducing the petroleum fuel consumption, and toxic and emissions of greenhouse gases.
Based on the importance of HEV, a high output torque HEV system and 20 kW brushless direct current (BLDC) motor is studied in this thesis. For the high power system requirement, a 20 kW high power motor driver with high torque output will be established. On the other hand, the HEV system needs a high performance controller. This controller can provide the stable and robust property. The overall electric controller of the HEV system can achieve the effect of the energy conservation.
It should be pointed out that although the low power BLDC motor driver research and design are already complete, compared the high efficiency type over ten thousand Watts BLDC motor driver research were still few. As everyone knows, the high power motor driver is more complicated for the low power driver of motor system. In this thesis, it is achieved several important tasks in the high power driver system design and implementation.
In this thesis, the experimental platform of the novel HEV system is already established. By way of the experimental platform test, we had completed the driver of the high performance. Finally, the novel HEV system achieve the energy saving and carbon reduction.
