摘　　要：对高功率带绕式脉冲变压器磁芯的设计进行了初步考虑,从理论上分析了在高功率带绕式空芯脉冲变压器中加入部分磁芯对变压器内部电磁场分布及耦合系数的影响。理论分析和实验结果均表明:磁芯对高功率带绕式脉冲变压器耦合系数的提高有显著作用,并能改善变压器内部的电磁场分布;设计的高功率带绕式脉冲变压器耦合系数可达0.88,与相同结构尺寸的带绕式空芯脉冲变压器相比,耦合系数提高10%。The paper discusses the magnetic-core structure of high power pulse transformer and its magnetic-core material selection. The effect of magnetic core on the distribution of transformer electric and magnetic field and the coupling coefficient is theoretically simulated and analyzed. The experimental and theoretic results indicate that the coupling coefficient is increased and the distribution field is improved by using magnetic core. In this case, the coupling coefficient of the transformer with magnetic core is up to 0.88. Compared with air-core transformer of the same size, its coupling coefficient increases 10%.
