PID controller based current sharing in Luo converter for standalone photovoltaic system

This paper emphases current sharing in Luo converters which are linked in parallel manner with solar input. The photovoltaic system supplies electric power which depends on the solar radiation and temperature. The suggested scheme comprises of dual parts, the first part is PV system followed by converters joined in a parallel manner at output to produce more current. For segmenting the current at output equally between two converters, the control structure has two control loops, a current loop and a voltage loop. P, PI and PID Controllers are designed for current and voltage loops and compared through MATLAB based simulation and PI is found to be satisfactory.
