| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 95 === This paper presents a new improved Miller switched reluctance motor(SRM) driver with continuous- conduction-mode charge-pump power factor correction (CCM-CP-PFC). At high duty-cycle, the phase current of original Miller SRM driver discharges slowly, which causes large negative torque, high power losses and low electromechanical conversion efficiency. In order to solve this problem, this paper proposes a new improved Miller SRM driver using auxiliary inductor and capacitor achieves phase current to discharge quickly. Moreover, the input current harmonics of the improved Miller meet IEC 1000-3-2 Class-D standard by integrating CCM-CP-PFC with improved Miller SRM driver. Based on the derived analysis of the proposed CCM-CP-PFC
improved Miller SRM driver, the design and the implementation of a prototype circuit is provided to demonstrate the performance of the proposed SRM driver.
