Abstract


Abstract

In this work, a simulation study of Maximum Power Point Tracking (MPPT) with Ripple Correlation Control (RCC) technique has been done. Photovoltaic (PV) array along with the DC/DC buck converter and its Maximum Power Point Tracking (MPPT) control strategy has been implemented with RCC for various solar radiations at 25oC, and simulations results are presented. RCC with low pass filter and tuned with Proportional Controller (PI) has been implemented. Simulation results show RCC removes all ripples from voltage, current and power outputs, which was the major concern of conventional MPPT techniques.
