According to grid-connected inverter current closed-loop system’s Bode diagram and zero-pole diagram, analysis was made to the stability of its current inner closed-loop system and experimental verification was carried out for PI parameters obtained from the method design. Experimental result shows that the double closed-loop PI regulator parameters design method is good in effect, being able to meet system design requirements. Key
