Efficiency Improvement of Wireless Power Supply Track System

We investigated a wireless power supply track system for automated guided vehicles. Due to the inherent limitations of wireless power transfer, its transmission efficiency is lower than that of contact-based power supply methods. To meet energy conservation and carbon reduction requirements, we proposed methods to improve the overall system efficiency. Different from the traditional design of adding inductor or capacitor filter circuits after the rectifier circuit, this paper proposed an improved circuit structure for the pick-up end. Through theoretical analysis and discussion using two methods, valley-fill filter circuits or directly removing the filter circuits, hardware experiments have verified the feasibility of the proposed method.
