基于双拾取线圈的二维感应式移动供电系统恒功率输出研究
|
摘要
为了在耦合结构不转动的情况下实现二维空间上的恒功率输出移动供电,根据Maxwell仿真优化X和Y方向移动时的互感波动情况,以最小功率波动为设计目标,设计了一种消除交叉耦合的新型双拾取线圈。搭建400W原理样机,考察二维方向上系统移动恒功率输出特性,发现系统输出功率的波动始终介于设定的±2.85%以内,系统效率最高为89.62%,与理论分析一致。实验结果验证了该方法的可行性。
In order to realize dynamic charging in two dimensions without rotating pickup, as well as to maintain constant output power, a novel pickup coil structure without cross coupling was proposed in this paper. Software Maxwell was used to decrease the mutual inductance pulsation for reducing the system output power vibration. A 400 W prototype was built to validate the proposed method. Experiment results show that the fluctuation of system output power is always within the set range of ±2.85%, and the maximum system efficiency is up to 89.62%. It demonstrates that the proposed method is effective and feasible.
