【摘要】：传统的单激励线圈系统有传输距离和传输角度的限制。为了解决这一问题,提出了四线圈激励的无线电能传输系统。通过将4个激励线圈分别放在平行和垂直位置的方式,不仅可以延长能量传输距离,而且减弱了传输方向的敏感度。为简化分析,将激励线圈等效为磁极,根据N/S极性,提出了区域线圈的4种绕组连接方式,通过理论分析和仿真,对其区域磁场分布进行研究。给出了区域等效电路模型,对比单激励线圈系统,推导出参数设计方法,给出了补偿电容的计算依据。以获取最大磁场强度为目标,选取S-S-N-N绕组连接方式,构建了一个0.8m×0.8m×0.8m的四线圈激励的共振式无线能量传输区域,验证了参数设计的正确性,并说明了采用四线圈构建供电区域可延长传输距离,减弱传输方向的敏感度。
[Abstract]:In order to solve this problem, the traditional single-excitation coil system has the limitation of transmission distance and transmission angle. A four-coil excited radio energy transmission system is proposed. The energy transmission distance can not only be extended by placing the four excitation coils in parallel and vertical positions respectively. In order to simplify the analysis, the excitation coil is equivalent to the magnetic pole. According to the N / S polarity, four kinds of winding connection modes of the area coil are proposed, and the theoretical analysis and simulation are carried out. The regional magnetic field distribution is studied. The regional equivalent circuit model is given. Compared with the single excitation coil system, the parameter design method is deduced. In order to obtain the maximum magnetic field intensity, the S-S-N-N winding connection mode is selected. A resonant wireless energy transmission region of 0.8m 脳 0.8m 脳 0.8m is constructed, which verifies the correctness of the parameter design. It is shown that the transmission distance can be prolonged and the sensitivity of transmission direction can be reduced by using four coils to construct power supply area.
