摘要
数字用户线(xDSL)已广泛用于网络通信技术。总谐波失真(THD)是xDSL技术中调制解调器用变压器的一项非常重要的参数。文章首先介绍了总谐波失真的概念和测试方法,然后叙述了变压器用铁氧体磁心材料、磁心形状和变压器外电路设计对总谐波失真的影响,指出了改善变压器总谐波失真的一般途径。
Digital subscriber line (DSL) has been applied widely to internet telecommunication technology. Total harmonic distortion (THD) is a very important design parameter of transformer in modem of DSL technology. At first the concept of THD and measuring method were introduced in this paper. And then the effects such as ferrite core materials, shapes of cores and external circuit design of transformers on THD were described. The general methods were introduced to improve THD of transformers.
