摘要

本論文的目是研製一種單相光伏並網換流器，採用d-q轉換相位控制無功功率控制。光伏換流器的驅動和控制係採用數位信號處理技術。本文採用帕克和克拉克轉換方法分析以三相轉換為基礎的單相光伏換流器。最後，針對三相模型用於單相換流器框架的設計考量和數位控制進行了探討。因此，成功地實現了一部具無功控制的1 kW光伏換流器，其輸出電流能夠領先和滯後電網電壓。

The purpose of this thesis is to develop a single-phase grid-connected PV inverter with reactive power control using d-q conversion phase control. Drive and control for the PV inverter is using digital signal processing techniques. This thesis adopts Park and Clarke transformation methods to analyze a three-phase conversion-based single-phase PV inverter. Finally, design considerations and digital control architecture for a single-phase three-phase model framework are explored. Consequently, a 1kW PV inverter with reactive control is successfully performed to make the output current be able to lead and lag the grid voltage.
