Design of a DC-DC converter for photovoltaic solar system

This paper proposes a full bridge dc/dc converter topology for photovoltaic cell. Photovoltaic dc/dc is a very crucial part of power conditioning system (PCS). The dc/dc converter is provided to regulate the constant output voltage under various operating conditions of photovoltaic cell. The voltage rating of power switch (MOSFET) for dc/dc converter is selected on the basis of photovoltaic cell's maximum output voltage. PV power conditioning system should have high efficiency under different operating conditions. An isolated dc/dc converter topology is proposed to satisfy PV PCS condition. The performance of the system is studied through simulation in MATLAB/SIMULINK.
