How is a three-phase PV Grid-connected inverter designed?
The three-phase PV grid-connected inverter was designed based on the LQR method, where the tracking error was adjusted to zero through integration (Al-Abri et al., ). The disturbance rejection ability of the PV GCI was improved by designing the linear state inaccuracy feedback control policy (Zhou et al., ).
Can a three-phase inverter synchronize with a conventional AC grid?

How does a grid-side inverter work?
The grid-side converter transfers the power from the DC-link into the grid through an LCL filter, and maintains the DC-link voltage at 800 VDC. The control scheme for the grid-side inverter comprises a two-loop configuration with an outer loop for voltage control and an inner loop for current control.
