【摘要】 交叉换位技术广泛应用于高频变压器绕组设计。本文从电磁场能量的角度出发,分析了交叉换位对变压器绕组交流电阻和漏感等参数的影响。推导出了只与线圈尺寸、原副边相对位置及电流变比等结构参数有关的KR、KL等系数来表征线圈交流电阻和漏感随交叉换位技术的变化情况。实例计算结果证实线圈交流电阻、漏感的变化分别与KR、KL呈线性关系,表明这两个指标可以反映出绕组交流电阻和漏感的变化规律。更多还原

【Abstract】 Interleaving skills are frequently used in the design of windings of high-frequency transformers. From the viewpoint of electromagnetic energy in and between the windings, the effect of interleaving on the windings’ AC. resistor and leakage inductance are analyzed. Two factors deduced can separately be used to present the varying trend of the two parameters corresponding to different interleaving ways. Thus, we can arrange the winding strategy validly without winding a coil each time.更多还原
