Abstract
modelling of the buck converter in photovoltaic power conditioning system is not a possibility of doing with input-output relationship from existing procedures. Because the input current and voltage of the buck converter in fluctuate at any time. The controller which design with the method which has like this error cannot have a good efficiency. In this paper, firstly, in order to design accurate controller of buck converter, new model is proposed. The modeling used a state-space averaging method and came to accomplish. Secondly, the process which design the controller is described. Finally, the simulation results are analyzed.
