适用于多种负载的感应耦合充电系统设计
Design of an Inductively Coupled Charging System for Multiple Loads
摘要: 针对未来家居环境需进行非接触充电的物品种类多且充电过程具有随机性的特点，设计了适用于多负载感应充电的无线电能传输系统。该系统的原边采用
LC串联结构，电源输出频率固定。副边的多个充电负载在空间上采用分布式结构，避免负载之间的耦合。为了适应阻抗变化导致的系统失谐，各负载配置独立调谐机构并采用最大电流模式自动调谐，保证充电过程的稳定和高效。
Abstract: Given the characteristics of future home environments, where a large variety of devices require contactless charging and the charging process is random, a wireless power transfer system suitable for multi-load inductive charging is designed. The primary-side of the system adopts an LC series structure with a fixed power supply frequency. Multiple charging loads on the secondary-side are configured in a distributed spatial layout to avoid coupling between coils. To address system detuning caused by impedance variations, each load is equipped with an independent tuning mechanism and uses maximum current mode automatic tuning, thereby ensuring stable and efficient charging processes.
