In a significant advancement for portable solar power systems, researchers have unveiled a groundbreaking on-chip power meter designed specifically for photovoltaic power generation. This innovative device, developed by Gisela de la Fuente-Cortes and her team at the Benemérita Universidad Autónoma de Puebla (BUAP), promises to enhance the efficiency of Maximum Power Point Tracking (MPPT) in DC-DC converters, a crucial component in optimizing solar energy output.
The power meter operates by estimating average current consumption, leveraging the discrete-time nature of the DC-DC control system. This approach not only simplifies the structure of the integrated chip but also enhances the accuracy of power measurement, a feat that could have far-reaching implications for the solar energy sector. “Our design aims to provide a reliable and efficient solution for portable systems, ensuring that they can harness solar energy more effectively,” de la Fuente-Cortes stated, highlighting the potential benefits of this technology.
The chip, synthesized using a 65nm CMOS process, exhibits remarkable efficiency, consuming only 5 percent of the overall DC-DC control system’s power under bias conditions of 1.2 volts. This low power consumption is particularly vital for remote electronic devices that rely on alternative energy sources, making solar power more accessible and practical for everyday use. The implications for commercial applications are immense, as this technology could lead to more compact and efficient solar power solutions in everything from handheld devices to larger off-grid systems.
As the world increasingly turns to renewable energy sources, innovations like this on-chip power meter are critical in ensuring that solar technology can compete with traditional energy sources. By improving the performance and feasibility of solar systems, this research not only paves the way for advancements in energy efficiency but also contributes to the broader goal of sustainable energy solutions.
The findings were published in ‘IEEE Access’, a journal that showcases pioneering research in various fields, including electronics and energy technology.
