PV Based Design of Improved Positive Output Super-Lift Luo Converter

The growing demand has lead to increased use of renewable energy resources. Among all renewable energy resources, the photovoltaic(PV) power generation acts as a green source. This paper proposes the implementation of Improved Positive Output Super-Lift Luo converter (IPOSLC) with the solar panel. IPOSLC is a type of DC-DC converter in which the positive output voltage increases in geometric progression. In Positive Output Super-lift Luo Converter, the output is increased three times the input. But in Improved Positive Output Super-Lift Luo converter, the output is increased six times of the input which is specified by adding an inductor and diode. To track the maximum power from the PV cell, P&O method is employed. In this method, the duty cycle is calculated with the sensing of the panel voltage and current and the corresponding power values of it. This system is modelled and simulated using MATLAB/Simulink and validated with the theoretical calculations.
