Abstract :
The features of L filter and LCL filter of grid-connected inverter, and the limitation of the traditional direct output current control method are analyzed in this paper. Then, the model of the inverter with LCL filter and the input-output feedback linearization control method are proposed. Simulation results show that the method have both fast dynamic response and litter steady state error, as well as decoupled control without damping resisters.
