摘要

本論文主要研製一單相市電併網直流/交流變頻器，由全橋式變頻器與LCL濾波器組成，利用Texas Instruments TMS320F28035作為數位信號處理器，並且採用具有靜止軸電流控制器做為單極性電壓切換脈波寬度調變的命令。其設計規格為輸入直流電壓200 V，輸出電壓110 Vrms/60 Hz，額定功率800 W，功率開關切換頻率12 kHz。由模擬與實驗結果證明，在輸入直流電壓200 V及各負載條件下，變頻器效率高於90%以上，電壓總諧波失真小於5%。

The object of this thesis is to design and implement a single phase grid-tied DC/AC Inverter. The system is composed of a full bridge inverter with LCL filter and Texas Instruments TMS320F28035 as digital signal processor. The control scheme uses a stationary frame current controller as the unipolar voltage switching pulse-width modulation command. The design specifications are input DC voltage of 200 V, output voltage of 110 Vrms/60 Hz, power rating of 800 W, switching frequency of 12 kHz. Simulation and experimental results verify the control scheme can cope with input DC voltage 200 V and various load conditions, the inverter efficiency is higher than 90%, and the total voltage harmonic distortion is less than 5%.
