Dr Surla Vishnu Kanchana Naresh, Assistant Professor, Department of Electrical and Electronics Engineering, Mr Rambabu Kallelapu, Research Scholar, along with Dr Sankar Peddapati, Assistant Professor, from the National Institute of Technology Andhra Pradesh, has conducted an in-depth study on advanced power converter technologies for electric vehicle applications.

In their recent paper titled “A Family of Bidirectional DC–DC Converters with Quadratic Voltage Gain and Continuous Current Profiles for EV Energy Storage Systems,” published in Q2  journal, IEEE Journal of Emerging and Selected Topics in Industrial Electronics, with an impact factor of 4.0, they have developed a novel family of non-isolated bidirectional DC–DC converters featuring quadratic voltage gain, continuous current profiles, and enhanced efficiency, offering improved performance and design flexibility for EV energy storage and charging systems.

A brief abstract of research :

This work developed a new family of non-isolated bidirectional DC–DC converters with quadratic buck–boost voltage gain, continuous input/output currents, and a common ground. These converters offer high voltage gain, low device stress, and reduced current ripple, with different stress profiles providing design flexibility for EV energy storage applications. Their peak efficiencies in both discharging and charging modes confirm their suitability for EV charger applications.

Practical implementation the research :

The social impact of this research lies in promoting the adoption of clean and sustainable energy technologies. Improved power conversion systems help reduce energy losses, lower electricity costs, and support the integration of renewable energy sources into the power grid. This contributes to reduced carbon emissions and supports the transition toward environmentally sustainable energy systems.
