Abstract

本論文實現了一三相切換式磁阻馬達驅動電路，達到電動車功能要求，特色在於不需額外多加元件，運用馬達內部繞組當作電感，即可達到馬達運轉與電網對電池充放電之功能，其電路包含雙向直流直流轉換器、單電流感測半橋轉換器、具功因校正整反流轉換器。另一特色在於電流感應器的減少，其驅動電路只需一個即可控制N相磁阻馬達，並且在併網模式中運用特殊的取樣策略達到整流對電池充電的目的目的。再來探討切換式磁阻馬達的基礎原理、轉速控制、電流控制、導通提前角、功率因數較正、電流取樣策略、前饋訊號計算，利用電腦軟體PSIM進行模擬驗證後，評估實作的可行性，再由FPGA硬體電路晶片撰寫Verilog程式設計控制器，完成實作成果，並且與模擬比對分析其確實具有功能性。

This thesis presents the development of a Switched Reluctance Motor Drive System for Electric Vehicles(EVs) which targeting the Grid-to-Vehicle (G2V), Vehicle-to-Grid (V2G),and Motor driver technologies.The circuit combines the bidirectional dc/dc converter, single current sensor asymmetric half-bridge converter, with switched reluctance motor. The characteristic of this circuit is using embedded components of SRM windings and asymmetric half-bridge converter to build V2G/G2V capabilities without extra circuit elements.Additionally,this driver system can through single current sensor to control N-phase motor and charging battery with sampling strategy. Some key issues of switched reluctance motor, speed control, current control, advanced shift angle,current sampling strategy and power factor correction are introduced and discussed in this thesis.All the controllers are implemented in Field Programmable Gate Array (FPGA). The provided simulation and experimental results show that well performances of the target.
