A recent study published in ‘IEEE Access’ has unveiled an innovative wireless power transfer (WPT) system that could significantly enhance the efficiency and reliability of energy transmission, especially in scenarios where alignment between power sources and receivers is less than perfect. The research, led by Veli Yenil from the Electronics and Automation Department at Pamukkale University in Turkey, introduces a dual side variable inductor (VI) control mechanism that allows for high efficiency and output power regulation.
Traditional wireless power systems often struggle with misalignment, which can lead to energy losses and reduced performance. However, the new LCC-LCC WPT system designed by Yenil and his team addresses this challenge by using variable inductors on both the primary and secondary sides. This design not only maintains zero voltage switching (ZVS) for the primary side inverter but also allows for effective output regulation despite misalignment. “By adjusting the inductances of the VIs, we can control the output voltage and current, ensuring efficient power transfer even when the devices are not perfectly aligned,” Yenil explained.
The implications of this technology extend beyond technical improvements. With a prototype capable of delivering 300 watts and achieving a maximum efficiency of 92.5%, the commercial potential is significant. Industries such as consumer electronics, electric vehicles, and renewable energy could benefit from this advancement. For example, electric vehicle manufacturers could integrate this technology into charging stations, allowing for more flexible and user-friendly charging experiences. Similarly, the ability to transfer power wirelessly in environments with misalignment could revolutionize how we think about powering devices in homes, offices, and public spaces.
Moreover, the elimination of additional compensation elements and the need for wireless communication between the primary and secondary sides simplifies the overall system design, potentially reducing costs and increasing reliability. This could lead to broader adoption of wireless power systems in various sectors, paving the way for a more connected and efficient energy landscape.
As the energy sector continues to evolve, innovations like this one from Yenil and his team represent a crucial step toward more sustainable and user-friendly power solutions. For those interested in further details, the full study can be accessed in ‘IEEE Access’.
