Performance of Different Types of DC – DC Converter with P & O Algorithm of MPPT

This comparative study analysis of dc-dc converter for MPPT controller with P and O algorithm of a grid connected system finds the better suitable converter which can give the output with maximum power from the PV module and can have reliability to connect it to the GRID. In this paper the performance of LLC, ZETA and SEPIC converters are designed and simulated then its results are compared to identify the best suitable converter for the grid connected PV with P and O algorithm of MPPT circuit. The performance analysis has been carried out by connecting these converters in the circuit which already simulated for connecting the PV output to the commercial grid. The comparative performance analysis is done at the stage of gird as well as in the stage of output of the converter too.
