摘要 当感应电能传输(inductive power transfer, IPT)系统为轨道机车负载供电时,其发射线圈通常采用长D型结构,但D型结构作为发射线圈会产生严重的电磁干扰问题,本文利用8字型线圈结构作为发射线圈,同时考虑到利用传统D型接收线圈时,因发射线圈与接收线圈间的互感值变化幅度大,使得其IPT系统输出功率严重失衡甚至无功率输出,这样严重影响IPT系统的稳定运行,因此本文将DDQ型结构作为接收线圈以改善IPT系统的功率特性。最后,构建一个基于8字型发射线圈以及DDQ型接收线圈的IPT实验系统。实验验证了该方法可以有效改善其功率特性。
Abstract:When inductive power transfer (IPT) system serves forthe IPT system serves for rail locomotive, D-type is usuallyused as the transmitter coil and receiver coil. For the transmitter is long, it can result in serious electromagnetic interfere (EMI) issues. Therefore, a 8-typetransmitter coil is applied in IPT system. Because mutual inductance between transmitting coil and receiving coil changessharply, it seriously affectsIPT system output power. Therefore, the DDQ-type coil is used as the receivercoil to balance the output power of IPT system. Finalliy, an IPT experimental system based on 8-type transmitter coil and DDQ-type receiver coil is constructed, and the experimental results show that this method can effectively improve the output power performance.
