Patent on Controlling DC-DC Buck Power Converters
The patent titled “A System to Control Dc-Dc Buck Power Converter And A Method Thereof” by research scholar K Mounika Nagabushanam, and Assistant Professors, Dr Somesh Vinayak Tewari, and Dr Tarkeshwar Mahto with application no: 202441098288 presents an innovative approach to managing power conversion in renewable energy systems extending its applications in electric vehicles and microgrids, highlighting the importance of robust power control in advancing sustainable energy technologies.
Abstract
The work disclosed a system to control DC-DC buck power converter and a method thereof. The system comprises a photovoltaic (PV) panel, a first DC-DC buck converter for voltage step-down, and a battery for energy storage. A bidirectional DC-DC converter manages power flow between the battery and the source bus, while a second bidirectional converter exchanges power with the AC grid. The load bus integrates a second DC-DC buck converter to regulate power for constant power loads and resistive loads. Switching components like IGBTs controlled through PWM signals, ensure precise power control. Inductive and capacitive elements stabilize voltage, filter ripples, and reduce noise. The system supports adaptive power distribution and robust load handling, ensuring efficient energy management.
Explanation in layperson’s terms
Passivity-based control (PBC) is a control technique applied to buck converters within renewable energy systems to maintain stability and efficiency despite varying input conditions. Buck converters are essential for stepping down fluctuating voltage outputs from renewable sources, such as solar panels, to a consistent level suitable for storage or direct use. In solar power systems, PBC is used to manage the voltage conversion from solar panels to batteries or the grid. It stabilizes the voltage output, ensuring efficient battery charging and smooth integration with the electrical grid. PBC’s application in renewable energy systems demonstrates its critical role in advancing sustainable energy technologies, providing a reliable and efficient power supply.
Practical and Social Implications
The proposed control can be used in Electric Vehicle, Microgrid applications to stabilize voltage under load variations.
Future research plans
Future research plan is to work on the testing of proposed control with high level DC-DC converters

Synthesising Flexible Solid-state Electrolytes for Electronic Devices
Dr Chinmoy Das, Assistant Professor from the Department of Chemistry, and scholars Mr Sushant Wakekar and Mr Sasikumar K have published their invention titled “Li-based solid-state electrolyte and a method for its preparation” in the Indian Patent Office (Patent application No. 202441083351). The invention illustrates how to synthesise inexpensive Li(I) ion-based solid-state electrolytes that are feasible for fabricating flexible electronic devices. The team worked on inexpensive and readily available starting materials that provide self-supported and flexible solid-state electrolytes to advance LIB applications.
Abstract
In our invention, we described a rapid and robust synthetic methodology to prepare novel flexible solid-state electrolytes (SSEs) suitable for the fabrication of eco-friendly lithium-ion batteries (LIBs). The mechanically flexible film has been synthesized upon in situ incorporation of Li(I) ion into two inexpensive biocompatible polysaccharide matrices through mixing. We achieved Li(I) ion-based superionic conductivity at room temperature which is feasible for the fabrication of flexible electronics in modern age society.
Practical Implementation/Social Implications of the Research
This invention can be implemented in various industries, such as electric vehicles (EVs), wearable and flexible electronics, and aerospace and aviation.
The team is extending their research towards the fabrication of cheaper sodium (Na+), potassium (K+)-ion based solid-state electrolytes with superionic conductivity and implementing them in designing the biodegradable sodium-ion / potassium ion batteries (NIBs / KIBs).
