Abstract
PV-based power generation is implemented in many places due to the exhaustion of carbon-based fuels and ecological challenges. The solar panels for electric power generation along with the battery for storing the extra power will help society during the future demand. This paper analyzes a tri-port converter and designs it for buck-boost operation using inductors and switches in the circuit. The voltage converter is designed to have electric Energy transfer from solar panel to LED lamp, solar panel to battery and battery to LED lamp. The voltage ratio of the proposed buck-boost voltage regulator is designed to be more as compared with the conventional buck-boost converter. Also, the proposed buck-boost Voltage regulator output voltage polarity is found to be the same as compared to the input voltage. The working battery is developed to have a bi-directional power flow to deliver power to the LED lamp and to store power from the solar panel. The switches are operated alternatively and make the mode of operation strategy simple. The design of the converter stability analysis of the system using a bode plot is done. The experimental results acquired from the prototype validate the design of the converter.
