摘要

本研究提出全新之單級驅動無刷直流馬達驅動系統整體設計。為了配合單級驅動電路設計，本論文之無刷直流馬達之定子線圈極性與現有直流無刷馬達之線圈有部分相反。依據此新式無刷直流馬達之線圈極性，本論文再提出單級驅動電路，此驅動電路整合了交直流轉換以及主動式功因調整功能之升壓電路，以及驅動於單一極整合設計。

此一全新的架構與馬達，全然不同於目前市場上主流的設計，將原先之多組控制器整合到馬達驅動電路中，並具有原本多級式電路的良好之功率因數以及馬達驅動能力的特性，進一步節省成本，突顯出交流用單級式直流無刷馬達系統之價值。

This study investigates the drive system of single stage brushless direct current (BLDC) motor. In order to go with the design of single stage driver circuit, polarity of some stator coils of the BLDC motor are reversed as compared with the original BLDC motor. According to the coils polarity of new type BLDC motor adjustment, we also propose a drive circuit for this motor, integrating AC to DC converter, boosting converter, active power factor correction and BLDC motor driver. The innovative driver circuit structure and motor are totally different from the mainstream products in the market. To integrate multi-stage controllers into a single stage motor drive circuit can also keep performance of PFC. Besides, the single stage BLDC motor system is much cheaper than the original multi-stage one. Experimental results demonstrate the effectiveness of the proposed BLDC system as expected.
