摘要:
沿电缆-底盘传导的共模电流是电动汽车产生电磁干扰的重要原因. 根据传输线理论,提出了利用电磁损耗抑制共模电流的新途径. 实践中,采用集总元件的梯形网络,在电容器和线圈内分别填充电损耗材料和磁损耗材料,来构建相应的电磁损耗器件. 通过求解基于传输矩阵关系式的联立方程组,探讨电磁损耗对电缆上共模电流影响的特征,表明利用电磁损耗可有效地抑制较宽频率范围内的共模电流. 本文提出的方法也可用于抑制光伏并网、舰船电力系统、印刷电路板等方面存在的共模电流.
Abstract:
The common mode current conducted through chassis and cables is a major cause for electromagnetic interference in an electric vehicle. Based on the transmission line theory,we suggest a new approach to suppress common mode current by using electromagnetic losses. In practice,the lumped-elements ladder network with the coils filled with magnetic lossy materials and the capacitors filled with electric lossy materials are adopted to construct the corresponding device. The effects of the electromagnetic losses on common mode current existed in chassis and cables are discussed by solving the simultaneous equations of the transfer matrix ones. The results show that the electromagnetic losses can effectively suppress common mode current in a wide frequency range. This method can also be used to suppress the common mode current existed in photovoltaic grid connected inverter,ship power systems,printed circuit boards,and so on.
