An approach for reducing parasites coupling between coupled transmission lines employed in power electronics

Abstract

Electromagnetic interference such as crosstalk are big problem for the control of components in power electronics. In this work, a new approach for reducing parasites coupling between coupled transmission lines employed in power electronics is presented. We proposed a new method for crosstalk reduction in PCB cards. This method is to add a tee guard line (TGL), between the coupled microstrip lines. This method has reduced much crosstalk. The NEXT is reduced about 78% and the FEXT about 82%. Also the crosstalk peak is reduced by about 82%. In this context, simulations are developed under the electromagnetic simulator. Followed by measurements made by a vector network analyzer (VNA), on various PCB cards.
