Description

一种新型单方向绕线耦合器的轨道车无线充电系统
技术领域
本发明涉及轨道车充电领域，尤其涉及一种耦合器单方向绕线的轨道车无线充电系统。
背景技术
近年来，电动汽车无线充电(WPT)技术在电动汽车快速发展的趋势下，以其安全节能的优势愈益受到重视，成为了电动汽车领域关注和研究的热点之一，并逐步运用到各种汽车供电场合。无线充电是将电能转换为高频磁场能，经过磁场的耦合被转化的电能透过空气气隙将能量进行传输。实际应用中，铺设于地的地面发射耦合器轨道和安装于车体的接收耦合器按照普通的多匝线圈绕线方式绕线时相邻两匝线圈间的电流方向一致，根据安培定则，相邻两匝线圈见的磁场会因存在相互干扰抵消的现象，从而造成了能量耗散影响无线充电系统的效率。
考虑到普通多匝线圈绕线方式的耦合器存在的缺陷，本发明单方向绕线耦合器的轨道车无线充电系统在轨道车无线充电过程中采用的地面单方向绕线发射耦合器轨道与车载单方向绕线接收耦合器的绕线方式均为单方向圆圈绕线。采用这种新型的耦合器绕线方式后，任意相邻线圈的电流方向一致，根据安培定则，线圈间的磁场被加强，这将有效解决普通多匝线圈绕线方式下相邻两匝线圈存在磁场相互干扰造成能量耗散缺点。现有的电动汽车无线充电技术大多停留在理论阶段，对于实际应用中利用单方向圆圈绕线的新型耦合器以减少线圈间的干扰提高能量传输效率的方法暂时没有人提及。
发明内容
本发明所要解决的技术问题是针对上述背景技术的不足，提供了一种新型单方向绕线耦合器轨道车无线充电系统。为了实现上述目的，本发明采用了如下技术方案：
一种耦合器单方向绕线的电动汽车无线充电系统，其特征在于，包括逆变器1、地面单方向绕线发射耦合器轨道2、车载单方向绕线接收耦合器3、整流调理装置4、车载电池5。所述逆变器从电网接收能量，变流后将能量传送到绕线方式为单方向圆圈绕线的地面发射耦合器轨道；所述车在单方向绕线接收耦合器绕线方式与地面发射耦合器导轨一致，当轨道车载导轨上运行时，接收耦合器接收地面单方向绕线发射耦合器导轨传递的能量；所述整流调理装置与车载单方向绕线接收耦合器相连接，经过整流调理后将电能传送到车载电池进行无线充电。一种新型单方向绕线耦合器轨道车无线充电系统实现方法包括以下步骤：
(1)轨道车在轨道行驶过程中，逆变器由电网接收能量，变流后将能量传送到地面单方向绕线发射耦合器轨道；
(2)车载单方向绕线接收耦合器与地面单方向绕线发射耦合器相对，接收地面单方向绕线发射耦合器轨道传递的能量；
(3)车体单方向绕线接收耦合器与整流调理装置相连接，接收耦合器接收的能量经过整流调理后传送到车载电池进行无线充电。
本发明采用上述技术方案，具有以下有益效果：地面单方向绕线发射耦合器轨道与车载单方向绕线接收耦合器采用单方向圆圈绕的线绕线方式后，有效解决了普通多匝线圈绕线方式下相邻两匝线圈间存在磁场相互干扰而造成能量耗散的缺点。

一种新型单方向绕线耦合器的轨道车无线充电系统实现方法包括以下步骤：
(1)轨道车行至充电轨道，逆变器从电网接收能量，变流后将能量传送到地面单方向绕线发射耦合器轨道；
(2)车载单方向绕线接收耦合器与地面单方向绕线发射耦合器相对，接收地面单方向绕线发射耦合器轨道传递的能量；
(3)车载单方向绕线接收耦合器与整流调理装置相连接，经过整流调理后将电能传送到车载电池进行无线充电。

步骤1：轨道车行至充电轨道；
步骤2：电压型逆变器从电网接收能量，进行变流工作；
步骤3：地面单方向绕线发射耦合器轨道接收逆变器变流后传递的能量；
