Single-Sensor Control of LCL-Filtered Grid-Connected Inverters [PDF]
IEEE Access, 2019 Owing to the filter resonance and background harmonics, the current control for the LCL-filtered grid-connected inverter should be carefully designed to ensure stable operation. Prior-art current control methods normally require extra sensors to achieve the damping of the resonance, or sophisticated active damping should be employed.
