| Abstract: | 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. |
