摘要：This paper proposes the simulation and implementation of performance enhancement of two phase interleaved boost converter using Maximum Power Point Tracking (MPPT) algorithm to achieve maximum power for Photo Voltaic ( PV) application. The output current is divided by two phase since current stress on each switch is reduced. Each switch is turn on by same frequency with phase difference of π. The output of PV panel is affected by temperature and insulation level, Hence conversion efficiency is very low. To improve the efficiency, additionally the MPPT controller is used in our proposed converter to efficiently draw the maximum power from the solar panel. The maximum power point is identified using Perturb &Observe (P&O) algorithm. The Perturb &Observe algorithm suitably to track the maximum power output of two phase interleaved boost converter with proper duty ratio. This paper present simulation and implementation procedure for two phase Interleaved Boost Converter with MPPT algorithm. The simulation results are obtained by using MATLAB/SIMULINK. The simulation results for non-isolated two stage interleaved high voltage gain boost converter were compared with and without MPPT. The MATLAB/simulink simulation results are presented to validate proposed converter. The hardware prototype of 12volt input 102 volt output has been developed.
