Design and Simulation of a 25/250V DC-DC boost converter fed by a PV pannel in SIMSCAPE library of MATLAB

The inevitable costs of using fossil fuels to generate electricity have led to attract lots of interest to the green energy sources recently. Due to high initial investment of solar power plant it is necessary to increase return of investment's rate by increasing the efficiency as much as possible. The use of PV panels has become very attractive as they provide a clean cheap form of energy. Controlling the O/P of a solar PV system is a key aspect so that the solar panel may be interfaced with boost converter to increase the overall efficiency of the system. The model presented in this paper is a physical modeling and simulation of solar PV system and DC-DC boost converter in SIMSCAPE library of MATLAB fed to an ohmic load. The proposed model is able to harvest solar energy using DC-DC boost converter to 250V which can be directly implemented to numerous loads as efficiency is improved.
