本文旨在研製具直流鏈補償之永磁式同步電動機驅動系統。文中之系統採用三相全橋型二極體整流器，將市電轉換為直流電源，並回授直流鏈電壓作脈波寬度調變補償控制，使其電壓/頻率控制之永磁式同步電動機轉速響應不受直流鏈變動的影響。本文之三相變頻器採用電壓空間向量脈波寬度調變技術，以提高直流鏈電壓之使用率及降低電動機之電流諧波含量。本文之系統亦選用適當的零電壓向量，以減少三相變頻器功率級開關元件之切換頻率，降低開關元件切換損失，以提高運轉效率。
　　本文以32位元數位信號處理器TMS320F2812為控制核心，完成系統之製作。三相變頻器及永磁同步電動機之控制策略皆由軟體完成，減少了電路元件。本文已完成輸出為600W，具直流鏈電壓回授之永磁式同步電動機驅動器，選用零電壓向量時，輸入平均值電流約下降0.25A。實測結果驗證本文系統之可行性。

This thesis presents the design of dc-link voltage compensated permanent-magnet synchronous motor (PMSM) drives. The full-bridge diode rectifier is used to convert the utility to dc source. The control of pulse-width modulation with compensation is completed by the feedback of dc-link voltage. Since the control of speed response PMSM is sensitive to the dc-link voltage variation, and is inefficient under voltage/frequency operation, the compensation of voltage is conducted to adjust the input voltage of inverter. The three-phase inverter adopts voltage space vector pulse-width modulation (VSVPWM) to raise the utilization factor of dc-link voltage and reduce the current harmonics of PMSM. In addition, compared to traditional VSVPWM, fewer zero-voltage switchings are used. This thus reduces switching loss of power transistors and increasing the efficiency of system operation.
　　The digital signal processor, TMS320F2812, is used to implement the proposed control functions. An experimental system of 600W with dc-link voltage compensation and novel zero-voltage switching technique is built. A reduction of 0.25A input average current is obtained using the proposed zero-voltage switching. The feasibility of the proposed system is verified experimentally.
