具超電容電動車開關式磁阻馬達驅動系統之開發

摘要　　本論文旨在開發一具蓄電池/超電容混合式能源之電動車三相開關式磁阻馬達驅動系統。除正常電動車驅動操作外，並利用電動車馬達驅動系統中既有元件組建整合式電路，具有電網至車輛及車輛至電網操作功能。所開發之馬達驅動系統，其開關式磁阻馬達非對稱橋式轉換器，由蓄電池經一交錯式直流/直流升壓轉換器供電。至於納用之超電容，以直流/直流降壓轉換器介接至馬達驅動系統之直流鏈，並透過二極體將超電容連接至蓄電池。在間歇及頻繁短期加減速下之能源轉換，可由超電容提供，因而有效地減少蓄電池充放電時間，有利於蓄電池壽命之延長。藉由適宜之切換和動態控制，以及換相前移和升壓策略，所建電動車馬達驅動系統具良好之驅動和煞車操控性能。　　當車輛處於閒置狀態，藉由適當地安排馬達驅動系統固有之功率元件，可從事具良好交流入電電力品質之電網至車輛充電操作。其電力電路由單相全橋式升壓型切換式整流器或單相無橋式升壓型切換式整流器和降壓轉換器為主之充電器組成。至於車輛至家庭操作模式，建構一具升壓直流鏈電壓之單相三線式變頻器，由變頻器產出60Hz 220/110V 交流電源以供給國內家電。採用差模及共模控制，在未知及非線性負載下，可得良好之輸出電壓波形。關鍵詞：開關式磁阻馬達、電動車、電動車載具、蓄電池、再生煞車、超電容、交錯式轉換器、單相三線式變頻器、功因校正、電網至車輛、車輛至家庭。

ABSTRACT This thesis develops a three-phase switched-reluctance motor (SRM) drive with battery/super-capacitor hybrid energy for electric vehicle (EV). In addition to normal EV operation, it possesses grid-to-vehicle (G2V) and vehicle-to-home (V2H) functions with integrated schematics constructed using SRM drive embedded components. In the developed motor drive, the asymmetric bridge converter fed SRM is powered by the battery through an interleaved DC/DC boost converter. As to the incorporated super-capacitor (SC), it is interfaced to the SRM drive DC-link via a DC/DC buck converter, and it is connected to the battery bank by a diode. This arrangement allows the energy conversions during intermittent and frequent short-duration acceleration/ deceleration be handled by the SC. It can efficiently reduce the discharging and charging times of the battery, hence the life of battery can be extended. Good driving operation and regenerative braking performance of the established EV motor drive are achieved by properly treating the switching and dynamic controls, commutation instant setting and voltage boosting. In idle condition, through properly arranging the embedded motor drive power devices, the G2V battery charging with good line drawn power quality can be operated. Its power circuit consists of a full-bridge boost switch-mode rectifier (SMR) or a bridgeless boost SMR and a buck DC/DC converter based charger. As to the V2H operation, a single-phase three-wire (1P3W) inverter with boosted DC-link voltage from battery is constructed to yield the 60Hz 220V/110V AC voltage outputs for domestic appliances. By applying differential mode (DM) and common mode (CM) control approaches, good output voltage waveforms are generated under unknown and non-linear loads. Key words: SRM, EV, EV load, battery, regenerative braking, super-capacitor, interleaved converter, single-phase three-wire inverter, power factor correction, grid-to-vehicle, vehicle-to-home.
