Abstract: This paper presents detail design of boost converter and proto-type development with optimized per turb (P&O) algorithms by using AT MEGA 8 microcontroller and the validation has been achieved by MATLAB/ Simulink. By using embedded function in sim power systems blocks the algorithms are developed, the developed algorithm which tracks point were the maximum power can extract from the PV panel or array through the designed boost converter which increases the input voltage with required output voltage with regulated manner, hence it maximizes the power generated by PV array.

Keywords: Photovoltaic system, Maximum power point tracking, Boost converter, solar cell.
