Design of Output Filtering and Repetitive Controller of Photovoltaic Inverter
The paper proposes the design method of output filter and repetitive controller of inverter in stand-alone PV system. The design of filter considers the impact of filter on the inverter main circuit in order to increase the stability of the inverter. For the serious waveform distortion when the inverter runs independently with non-liner load, the circuit introduces repetitive control and presents a new parameter design method of repetitive controller. The simulation results prove that the design method is correct and feasible.
