Inductive Wireless Power Transmission Device Design for High-Voltage Systems

Current power supply methods struggle to meet the needs for lightweight, isolated power delivery in high-voltage environments. To address this challenge, this paper proposes an Inductive Wireless Power Transmission Device Design for High-Voltage Systems. Initially, the design of the system is elaborated, utilizing an LC topology circuit to enhance both output power and efficiency. The reliability of the design was confirmed through simulation calculations. Subsequently, a prototype was developed that successfully delivered 75.5 W of output power with an efficiency of 94.3%. The experimental results indicate that the wireless power transfer system, as designed, successfully achieves high-power transmission with high efficiency while maintaining a high tolerance for insulation.
