Abstract-The utilization of inverters for the interconnection of distributed generators to the grid requires application of control systems capable of regulating the active and reactive output current, ensuring high power quality levels and achieving relative immunity to grid perturbations. To address the issue of high Total Harmonic Distortion (THD) in three-phase grid-tied inverters, this study proposes a novel three-phase LCL grid-tied inverter. The LCL filter circuit parameters are. . If I have a buck converter supplied with DC voltage ($V_ {DC}$), I can command the output voltage ($V_ {out}$) directly via the duty ratio ($D = V_ {out}/V_ {DC}$).
