Design & Implementation of Quadratic Boost Converter in Hybrid Renewable System

Abstract

The integration of renewable energy sources such as solar photovoltaic (PV) and wind turbines into modern power systems is essential to meet growing electrical demands and to address sustainability challenges. However, the inherent variability and low output voltage of sources like PV modules necessitate efficient power conditioning solutions for stable and reliable operation.

This paper presents the design and implementation of a quadratic boost converter (QBC) within a hybrid renewable energy system, enabling high voltage gain and reduced voltage stress on circuit components at lower duty cycles. The proposed QBC topology efficiently boosts and regulates the output voltage from combined renewable inputs, achieving four times voltage gain compared to conventional boost converters.

The project proposes the design of a quadratic boost converter that provides high voltage gain and efficiency. This converter has been fed with dual input of two renewable sources in parallel that can provide a solution to the issue of reliability related with renewable resources. A comparative analysis has been done on the performance of quadratic boost converter with conventional boost converter which highlights the beneficial advantages of the quadratic boost converter.
