碩士 === 崑山科技大學 === 電機工程研究所 === 99 === This thesis mainly studies the Switch Reluctance Motor (SRM) Driver System with SEPIC Power-Factor-Correction (PFC) Rectifiers. An active PFC rectifier based on a SEPIC converter with average current-mode control (ACC) technique is investigated in the thesis. It’s controlled by two feedback loops, a fast inner current loop and a slow outer voltage loop. When the system reaches well output voltage regulation under input voltage variation and loading change, it would comply with the international current standards on power factor and input current distortion of power supplies. Regarding the part of SRM Driver System, it is designed for the drive by using 3-phase 12/8 pole SRM with a full digital speed control based on DSP single chip dsPIC30F4011. The speed of motor estimation utilizes the rotor salient pole position of SRM to sense pulse signal. In addition, with the design of single-supply-driven circuit to save cost, the design of speed controller to reduce the effects of motor and parameter variations, the system provides a good performance even under load torque disturbance.
