Robust Dual-Load Wireless Power Transfer System Based on Parity Time Symmetry

Abstract
Utilizing electromagnetic fields, wireless power transfer (WPT) is an innovative technology that transmits electrical energy without physical connectors.The demand for mobile devices has fueled interest in multi-load WPT systems for dynamic applications.Parity-time (PT) symmetry, borrowed idea from quantum mechanics,is able to enhance WPT by optimizing resonant structures with gain and loss components. This work extends dual-load WPT using PT symmetry, creating a stable system with efficient power transfer to two loads simultaneously.The results show that the system is critically damped in strong coupling regions. In addition, the system simultaneously powers two loads at a high efficiency of 46% each when the coupling coefficients are balanced. Therefore, the total efficiency maintains about 92% independent of the coupling coefficient. Keywords - Parity-Time Symmetry, Dual-LoadWireless Power Transfer, High Efficiency.
