摘要

本文主要是研製具有單相輸入功率因數修正之永磁同步馬達驅動器，其中，功率因數修正是以升壓型交流-直流轉換器之架構為核心並輔以電流與電壓控制迴路，以提供馬達負載所需之功率。於直流鏈電壓回授加入陷波濾波器有效濾除二次諧波而提高電壓迴路之響應頻寬。另外，提出強健控制器進一步改善直流鏈電壓對負載擾動之抑制能力。
有別於傳統固定電壓輸出之功率因數修正，系統採用動態直流電壓升降輸出以建立動態升壓配合馬達之高速及加減速之運作。永磁同步馬達之速度調控是以簡易之霍爾元件作為轉子磁場位置回授，以鎖相迴路進行馬達速度估測及具有電流閉迴路控制以有效提升馬達驅動系統之動態響應。所提之控制策略則以數位訊號處理器以全數位方式實現並驗證所提策略之有效性。

The main purpose of this thesis focuses on implementation a PMSM drive with single phase power factor correction based on voltage-boost AC-DC converter. In the converter, both voltage and current control are used to enhance the control performance and provide power for PMSM. The dynamic response of the DC-link voltage is promoted using second-order Notch filter to minimize the appearance of second harmonics voltage ripple on the DC-link. Furthermore, a robust controller which is actuated by load transient current, is added to stabilize the DC-link voltage under load variation.
Compared to the conventional PFC converter with fixed DC voltage output, the proposed converter using dynamic voltage-boosting provides the extra voltage for motor in both high speed operation and speed accelerated/decelerated period. The speed control of a PMSM is based on three Hall-Effect sensors equipped on PMSM. And the rotor speed is estimated from Hall-Sensors using Phase-Locked loop (PLL). As for the current loop is utilized to further enhance the torque response such that dynamic response of motor drive can be improved. All the control schemes are fully digitally implemented in a DSP-based control environment which is constructed using a dsPIC 30F4011. Some measured results are provided to show effectiveness of the proposed methods in driving PMSM with PFC.
