In the ever-evolving landscape of energy storage and management, a groundbreaking development has emerged from the labs of Christ University. K. Suresh, a researcher from the Department of Electrical and Electronics Engineering, has introduced a novel stepdown/step-up converter designed to revolutionize the way we manage power in compact electronic devices. This isn’t just an incremental improvement; it’s a leap forward in efficiency and performance.
The converter, detailed in a recent publication in Scientific Reports, is engineered to optimize the runtime of series-connected batteries. As batteries discharge, their voltage drops progressively, often falling below the necessary operating levels. Suresh’s converter addresses this issue head-on by automatically transitioning between stepdown, step-up, and stepdown/step-up modes. “The key innovation here is the dynamic mode switching,” Suresh explains. “By minimizing the use of the less efficient stepdown/step-up mode, we’ve managed to achieve up to 93% power conversion efficiency, which is an 11% improvement over conventional models.”
But the benefits don’t stop at efficiency. The converter supports an output current up to 500 mA, a 67% increase compared to existing technologies. This means longer battery life and enhanced performance for a wide range of devices, from smartphones to wearable tech and beyond. The compact size of the converter, measuring just 1.44 mm by 0.73 mm, fabricated with 180 nm BCD technology, makes it an ideal solution for space-constrained applications.
The commercial implications of this research are vast. In an era where energy efficiency is paramount, a converter that can extend battery life and improve performance is a game-changer. Manufacturers of compact electronic devices stand to benefit significantly, as do consumers who demand longer battery life and better performance from their gadgets.
The converter’s ability to handle a wide input voltage range, from 2.5 to 8 V, and its incorporation of a capacitive coupling level shift circuit to protect the gate oxide layer of the power transistor, further underscores its robustness and reliability. “This converter is not just about efficiency; it’s about durability and versatility,” Suresh adds.
As we look to the future, this research could shape the development of more advanced energy management systems. The dynamic mode switching and high efficiency of Suresh’s converter set a new benchmark for what’s possible in power conversion technology. With further refinements and commercialization, we could see this technology integrated into a wide array of devices, from consumer electronics to industrial applications.
The publication of this research in Scientific Reports, a peer-reviewed journal, underscores its significance and potential impact. As the energy sector continues to evolve, innovations like this will be crucial in driving progress and meeting the growing demand for efficient and reliable power solutions.
