摘要

本論文旨在建立一具混合儲能源緩衝之單相切換式整流器供電開關式磁阻馬達驅動系統。首先建構一非對稱橋式轉換器供電之開關式磁阻馬達驅動系統，透過妥善設計及實現之電力電路及控制架構，具良好之驅動性能。此外，由適當之換相移位及升壓策略，增進馬達於高速與高載下之性能。再者，以SiC-MOSFET和傳統Si-IGBT組成之開關式磁阻馬達驅動系統，以實測進行效率比較評估，其間同時建議合適之開關式磁阻馬達驅動系統功率量測方式。
接著，建立一單相全橋切換式整流器作為開關式磁阻馬達驅動系統之主動式交流前級。於驅動模式下，有良好調節直流鏈電壓之馬達驅動系統具優越之驅動性能，以及良好之交流入電電力品質。同時，由於適當之控制及所採全橋切換式整流器具雙向功率能力，使再生煞車可成功執行，回收之馬達軸動能可回送直流鏈，再至市電。
再者，建立一混合式儲能系統，於驅動系統之直流鏈提供能量緩衝。所建混合儲能系統包含開關式磁阻馬達驅動飛輪、超級電容組與蓄電池組，各自經雙向介面轉換器介接至直流鏈。透過適當設計之電力電路及控制器，各儲能系統皆具良好充放電特性。最後，經所提之測量結果，展示所建具混合儲能源之切換式磁阻馬達驅動系統，於一些情況下之整體操作特性。

This thesis establishes a single-phase bidirectional switch-mode rectifier (SMR) powered switched-reluctance motor (SRM) drive with energy storage buffer. First, the asymmetric bridge converter fed SRM drive is constructed. After properly designing and implementing the power circuit and control schemes, satisfactory motor driving performance is preserved. In addition, the commutation shifting and voltage boosting are properly treated to enhance the performances under heavier load and higher speed. Moreover, the efficiencies of SRM drives constructed using SiC-MOSFETs and Si-IGBTs are comparatively assessed experimentally. Meanwhile, the adequate motor power measurement for an SRM drive is also suggested.
Second, a single-phase H-bridge switch-mode rectifier is established and used as the AC front-end of the SRM drive. In driving mode, the SRM drive having well-regulated DC-link voltage possesses good driving performance and satisfactory line drawn power quality. And the regenerative braking can be successfully operated thanks to the proper control for the SRM drive and the bidirectional capability of the employed H-bridge SMR. The recovered motor shaft kinetic energy can be sent back to the DC-link, then the mains.
Third, a hybrid energy storage system (HESS) is established to support energy buffer for the SMR-fed SRM drive at its DC-link. The established HESS consists of an SRM- driven flywheel (FW), a super-capacitor (SC) bank and a battery bank. Each storage device is individually connected to the DC-link via a one-leg bidirectional boost-buck interface converter. Through the properly designed power circuits and controllers, each of the established energy storage system possesses good charging and discharging characteristics. Finally, some measured results are provided to demonstrate the operating characteristics of the whole SRM drive equipped with the HESS in various conditions.
