Abstract

A DC-DC converter is an important constituent of a photovoltaic(PV) power system. Power generated by the PV system is a function of solar insolation, and temperature. Power-voltage (P-V) characteristic of a PV module exhibits a single power peak. A maximum power point tracking algorithm is required to operate the PV array at its maximum power point. The DC-DC converter works as an impedance matching circuit in between the PV array and load. A suitable selection of DC-DC converter is an important decision according to the application. In this study, a comparative analysis of different DC-DC converter is discussed in terms of efficiency, computational time, and complexity. A widely adopted Incremental conductance (INC) MPPT algorithm is used to evaluate the performance of each DC-DC converter. Performance of each converter in MPPT application is simulated using MATLAB/SIMULINK
