|a There is no easy way to convert Photovoltaic (PV) energy with high efficiency due to dynamic changes in solar irradiance and temperature. This paper illustrates a control strategy to design and implementation of Maximum Power Point Tracking (MPPT) in a photovoltaic system using Perturb and Observe (PandO) algorithm. The PSIM simulation results confirm proper functioning of the proposed MPPT sub-circuit to achieve a constant 48V DC output from fluctuating voltage of solar panel by varying duty cycle of the MOSFET in the 24V-48V boost converter. The filtered output waveform of the SPWM driven H-bridge inverter via the L-C low pass filter is found to be a pure sine-wave of 48V peak which is then stepped-up 312V peak (220V rms) by using a step up transformer. The frequency of output voltage is found to be 50Hz with a total harmonic distortion (THD) of 0.001 which is much lower than the IEEE 519 standard.
