Frequency Adaptive Current Control Scheme for Grid-connected Inverter without Grid Voltage Sensors Based on Gradient Steepest Descent Method
This paper presents a frequency adaptive grid voltage sensorless control scheme of a grid-connected inductive−capacitive−inductive (LCL)-filtered inverter, which is based on an adaptive current controller and a grid voltage observer. The frequency adaptive current controller is c...
