摘要 LCL滤波器由于具有滤波特性好、体积小的优势, 被越来越广泛地的应用于单相并网逆变器中, 但由于其电容支路极易产生谐振, 对控制电路设计提出了很大的挑战。从控制目标来分, 单相 LCL并网逆变器主要包含以下两类策略:电流控制型和电压控制型。目前, 大多数研究主要围绕单相锁相环及如何改善电流控制效果在进行。而本文主要针对控制目标的特性, 围绕不同控制策略的优缺点进行了全方位的说明和归纳比较, 并得出相应结论。

Abstract：LCL filter has been used in grid-connected single phase inverter for its good filtering performance and small size. However, capacitor branch may cause resonance, which leads greater challenges to control strategy. To the angle of control target, the control strategy of single phase inverter with LCL filter can be classified into two sorts, the current-controlled inverter and voltage-controlled inverter. Most researches make appropriate improvement based on PLL and controller technique. This paper summarizes and classifies these researches and makes conclusion.

Key words： Single-phase inverter LCL filter control strategy current-controlled voltage- controlled
