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
