Researchers from the Department of Computer Science and Engineering (Data Science) at Dayananda Sagar College of Engineering in Bangalore, India, have developed an innovative solar-powered high gain DC-DC converter that could significantly enhance the functionality of portable devices. Led by Vijayalakshmi Nanjappan, the team’s work focuses on improving energy efficiency and reliability in the face of fluctuating solar conditions.
The new converter design leverages a Field Programmable Gate Array (FPGA) to manage complex load control systems, enabling it to adapt dynamically to changes in solar irradiance. This is particularly crucial for portable devices that rely on solar energy, as inconsistent sunlight can disrupt power supply and device performance. The researchers employed a perturb and observe method combined with a load balancing algorithm to stabilize the input from photovoltaic panels, ensuring a steady output even when solar conditions are less than ideal.
One of the standout features of this converter is its impressive output gain ratio, achieving up to 14 with a minimum duty cycle of 40% at a switching frequency of 20 kHz. This means that the converter can effectively enhance the power output from solar panels, making it a promising solution for energy-hungry portable devices. “The dynamic panel input makes it difficult to operate the load,” Nanjappan explained, highlighting the challenge that many solar-powered systems face. “Our approach helps maintain a consistent power supply, even during fluctuations.”
The implications of this research extend beyond just portable devices. Industries that rely on renewable energy solutions, such as electric vehicles, mobile charging stations, and remote monitoring systems, could greatly benefit from this technology. The ability to maintain high efficiency and low ripple in power output would enhance the performance and lifespan of batteries used in these applications, reducing operational costs and improving user experience.
The research findings, published in ‘e-Prime: Advances in Electrical Engineering, Electronics and Energy,’ suggest a significant step forward in solar energy utilization. As the demand for sustainable energy solutions continues to rise, innovations like this converter could play a crucial role in shaping the future of energy-dependent technologies. The potential for commercial application is vast, opening doors for manufacturers and developers aiming to integrate more efficient solar-powered systems into their products.
