摘要

本論文旨在開發具聯網及能源收集功能之電動車開關式磁阻馬達驅動系統。前者包含電網至車輛、車輛至家庭及車輛至電網等操作。
馬達驅動系統由電池經交錯式升壓/降壓介面轉換器供電，具容錯能力。可升壓之直流鏈，增進了電池電壓之選擇彈性及馬達驅動系統之操控性能。蓄電池輔以超電容，減少其變動之充/放電操作。除再生煞車時之回充外，超電容亦可於定速時期進行補充。於電動車馬達驅動控制方面，除適當設計電流及速度控制架構外，亦妥善利用換相前移與直流鏈升壓策略降低高速及/或重載下反電動勢之影響。
另外，藉由所構裝之雙向諧振轉換器及三相變頻器，所開發之電動車馬達驅動系統得以施行雙向聯網操作。於電網至車輛操作下，車載電池可由單相或三相市電充電，而具良好之電力品質。反之，於車輛至家庭/車輛至電網操作下，所產生之60Hz單相/三相交流電，可供給家用負載，或回送預設之電能至電網。
最後，建立一基於三相維也納切換式整流器之插入式能源收集架構，車載電池之輔助充電電源可為可收集之三相交流源、單相交流源或直流源提供。

This thesis presents the development of an electric vehicle (EV) switched-reluctance motor (SRM) drive with grid-connected and energy harvesting capabilities. The former includes grid-to-vehicle (G2V), vehicle-to-home (V2H), and vehicle-to-grid (V2G) operations.
The motor drive is powered by the battery via an interleaved boost/buck one-leg interface converter with fault-tolerant capability. The battery voltage selection flexibility and motor driving performance enhancement are preserved due to boosted DC-link voltage. The battery is assisted by a supercapacitor (SC) bank in reducing its fluctuated discharging/charging operations. Except for the regenerative braking, the SC is also arranged to be charged during constant speed driving duration. In EV motor driving control, in addition to the properly designed current and speed control schemes, the commutation shifting and the voltage boosting are applied to reduce the effects of back-EMF under higher speeds and/or heavier loads.
A bidirectional CLLC resonant converter and a three-phase inverter are used to let the developed EV drive perform bidirectional grid-connected operations. In grid-to-vehicle (G2V) operation, the on-board battery can be charged from the single-phase or three-phase mains with good line drawn power quality. Conversely in vehicle-to-home (V2H) and vehicle-to-grid (V2G) operations, the 60Hz single-phase or three-phase AC voltage is generated to power the home appliances or send the preset power to the utility grid.
Finally, a three-phase Vienna SMR based plug-in energy harvesting mechanism (EHM) is developed. The auxiliary battery charging is provided from the possible harvested three-phase AC source, single-phase AC source or DC source.
