Abstract

The invention relates to the technical field of wireless power transmission, and particularly discloses an anti-offset coupling mechanism and an electric vehicle wireless charging constant voltage output control system, the coupling mechanism comprises a transmitting coil L1 arranged on a primary side, and a receiving coil L2 and a compensation coil L3 arranged on a secondary side, and the transmitting coil L1 and the receiving coil L2 are both square coils; the whole compensation coil L3 is a square coil and is symmetrically placed on the upper layer of the receiving coil L2 in a 45-degree staggered manner, so that four corners of the compensation coil L3 are equally extended from four sides of the receiving coil L2; and the compensation coil L3 consists of two bipolar coils, is decoupled from the receiving coil L2, and is also decoupled from the transmitting coil L1 under the condition that the transmitting coil L1 is opposite to the receiving coil L2. According to the coupling mechanism, the offset complementary characteristic of the receiving coil and the compensating coil is utilized, so that the sum of mutual inductance of the receiving coil and the compensating coil is kept approximately unchanged under the condition of large-range offset, and the system can keep constant-voltage output irrelevant to a load under the condition of large-range offset.

本发明涉及无线电能传输技术领域，具体公开了一种抗偏移耦合机构及电动汽车无线充电恒压输出控制系统，该耦合机构包括设置于原边侧的发射线圈L1，以及设置于副边侧的接收线圈L2和补偿线圈L3，发射线圈L1和接收线圈L2均采用方形线圈；补偿线圈L3整体为一个方形线圈，其交错45°地对称放置于接收线圈L2上层，从而补偿线圈L3的四个角均等地从接收线圈L2的四条边支出；补偿线圈L3由两个双极型线圈组成，与接收线圈L2解耦，在发射线圈L1与接收线圈L2正对的情况下与发射线圈L1也解耦。该耦合机构利用接收线圈与补偿线圈的偏移互补特性，使二者在大范围偏移情况下互感之和保持近似不变，可使系统在大范围偏移下保持与负载无关的恒压输出。
