摘要


本論文引用以數位訊號處理器為基礎之正弦脈波調變(SPWM)控制器以驅動市電併聯型單相太陽能換流器,並以數位比例-積分補償器對系統穩定度和諧波抑制提出分析與設計策略。針對系統控制與補償,本文以狀態平均法進行系統分析,並以MATLAB分析與模擬系統控制。最後實際製作一部1.5kW 的太陽能換流器以驗證理論分析與模擬。相較於類比式比例-積分控制,數位比例-積分控制對總諧波失真(THD) 的抑制確實有良好效果而且容易實現。

並列摘要


This thesis is to realize a single-phase PV inverter driven by using digital-signal-processor-based sinusoidal-pulse-modulation (SPWM) controller. Digital proportional - integral (DPI) compensator is employed for system stability and harmonic suppression, which builds the analysis and design strategy. For system control and compensation, state-averaged analyses for system analysis and MATLAB for system simulation are conducted, respectively. Finally, a demonstrated prototype of 1.5kW PV inverter is realized to verify the theoretical analysis and simulation. Compared to analog proportional-integral (PI) control, the DPI control to the total harmonic distortion (THD) suppression does have good results and easy to implement in real design.
