Abstract
Wireless power transfer (WPT) is a groundbreaking technology that enables energy transfer without the need for cords or cables. This innovative approach has the potential to revolutionize how we use energy in various applications, including portable electronics, medical implants, solar-powered satellites, electric vehicles (EVs), and unmanned aerial vehicles (UAVs). One of the most exciting aspects of WPT is its flexibility and ability to transfer power without the need for precise positioning. This means that devices can be charged or powered up even when they are not directly aligned with a power source. As a result of its versatility and convenience, WPT is considered an ideal solution for powering electric devices. The widespread adoption of WPT technology is applied in industries and homes. For the industries, it is commonly for the robotic gripper. Even though advanced technology is widely used in industries and homes, it inevitably faces limitations and challenges, prompting ongoing efforts to improve and innovate for example in this project is the high spike output voltages. Voltage tolerance limits are crucial in electronic devices, as surpassing them can lead to system failures and malfunctions. Thus, this work endeavours to enhance wireless power transfer (WPT) capabilities through the implementation of a closed-loop DC-DC buck converter within the WPT system. The primary objective revolves around augmenting power transmission efficiency by regulating the output voltage of the buck converter circuit. The research spans various domains, encompassing the development of a suitable DC-DC converter tailored for WPT applications. Moreover, the project delves into the design and analysis of closed
loop buck converters, with a specific focus on devising intelligent data-driven feedback control mechanisms. These controllers facilitate precise regulation of the
output voltage, a critical aspect in wireless power transfer scenarios. Furthermore, the project explores strategies to address WPT limitations, including the investigation of PID controllers and their behaviour to enhance system performance. Through this analysis, the importance of employing a controller with Improved stability and control for achieving optimal performance is underscored. The insights gleaned from these investigations furnish valuable guidance for future enhancements and refinements, shedding light on the system's behaviour and characteristics.
