本論文旨在開發一具再生剎車功能之雙向三相切換式整流器供電開關式磁阻馬達系統，並由混合式儲能源系統介接至其直流鏈，提升系統之供電可靠性及能源利用性。首先，建立一數位訊號處理器為主非對稱橋式整流器供電之開關式磁阻馬達驅動系統，以為測試平台。藉由適當設計之電力電路、感測及控制架構，所建系統具有正常操作及良好之驅動特性。再藉由得宜之換相移位及增壓策略，可再提升馬達於高速高載下之驅動性能。
接著，開發一具功因矯正之雙向交流/直流轉換器，其係由三相切換式整流器後接單臂降壓/升壓轉換器構成，作為開關式磁阻馬達驅動系統之交流前級。兩級轉換器之電力電路及控制機構均妥以設計及實現，在具良好入電電力品質下，馬達驅動系統具優良之驅動性能；同時，於再生煞車下，回收之儲能動能可成功回送市電。
最後，所建之混合式儲能系統於驅動系統之直流鏈處提供其能源緩衝。此儲能系統包含開關式磁阻電機驅動之飛輪、超電容組與蓄電池組，各經其雙向介面轉換器介接至直流鏈。藉由適當設計之電力電路及控制器，此混合儲能系統具有良好的充放電性能。於市電斷電時，馬達驅動系統由飛輪先提供能源支撐，其次為超電容；於功率型儲能耗盡時，蓄電池持續供能直到市電回復。所有電力組成之操控特性均以實測驗證之。

This thesis develops a switched-reluctance motor (SRM) drive powered by a bidirectional three-phase switch-mode rectifier (SMR) to have regenerative braking capability. It possesses improved power supplying reliability and energy utilization thanks to the equipped hybrid energy storage at DC-link. To be a test platform, a digital signal processor (DSP) based asymmetric bridge converter fed SRM drive is first developed. Normal operations and good driving characteristics are preserved by the properly designed power circuit, sensing schemes and control schemes. In addition, the commutation shift and voltage boosting are further properly treated to enhance the performances under heavier load and higher speed.
Second, a bidirectional power factor corrected (PFC) AC/DC converter consisting of a three-phase SMR and a followed one-leg buck/boost DC/DC converter is established. And it is used as the AC front-end of the SRM drive. The schematics and the constituted controllers of the two power stages are all adequately designed and implemented. Under satisfactory line drawn power quality, the SRM drive possesses good driving performance. And the regenerative braking can be successfully conducted with the stored kinetic energy being sent back to the mains.
Third, a hybrid energy storage system (HESS) is used to provide energy buffer for the SMR-fed SRM drive at its DC-link. The constructed HESS consists of a SRM-driven flywheel, a super-capacitor bank and a battery bank. All storage devices are connected to the DC-link through their bidirectional interface converters. Through proper designs of power circuits and controllers, the established energy storage system possesses good hybrid charging and discharging characteristics. As the grid power outage occurs, the motor drive can be first supported energy from the flywheel, then the super-capacitor is followed. As the power-type storage devices are exhausted their energies, the battery will succeed to discharge until the mains recovers. The operating characteristics of all power stages are verified experimentally.
