本文提出了一种采用电容式电力传输（CPT）技术的新型非接触式电池充电系统。目的是实现足球机器人的无干预能量补充系统。当足球机器人检测到电池电量低时，会自动导航到充电站充电。尽管感应电力传输 (IPT) 技术已针对此类应用进行了研究，但 CPT 技术提供了一种新的解决方案，可以跨金属屏障传输电力并减少电磁干扰 (EMI)。本文涵盖了用于产生高频电场的电源转换器的系统设计、初级电路与机器人上的电源拾取器之间的适当耦合以及拾取器电池充电。仿真和实验结果证明了所提出的非接触式电池充电系统的工作原理。
This paper proposes a novel contactless battery charging system using capacitive power transfer (CPT) technology. The aim is to achieve an intervention-free energy replenishment system for soccer playing robots. When the battery level of a soccer playing robot is detected to be low, it is navigated to the battery charging station to charge up automatically. Although inductive power transfer (IPT) technology has been investigated for such an application, the CPT technology provides a new solution which can transfer power across metal barriers and reduce electromagnetic interference (EMI). This paper covers system design of a power converter for high frequency electric field generation, proper coupling between the primary circuit and the power pick-up on board the robot, as well as the pick-up battery charging. Simulation and experimental results have proven the working of the proposed contactless battery charging system.
