Voltage source converters (VSC) are widely used in the distribution generation (DG) systems for the conversion of renewable energies. These converters are usually connected to the utility grid through a simple L filter to reduce the current harmonics injected to the grid. A LCL network, which can achieve reduced levels of harmonic distortion at low switching frequencies with less inductance, is a good alternative. In this paper, a three-phase converter with LCL filter is theoretically analyzed, and the corresponding state-space mathematic model is established. Furthermore, a hybrid controller incorporating repetitive control and state feedback pole-assignment control is proposed for the converter. Simulation and experimental results of the converter with LCL filter are provided to verify the validity of the proposed controller.
