Abstract

The transmission line busbar filter is a good choice for a high-density EMI containment solution. This paper presents a study of the application of a transmission-line busbar filter in a motor drive system. To examine the potential improvement for busbar filters, low-frequency attenuation and basic modeling of busbar filters in a motor drive are studied. Based on the knowledge gained from the modeling, an improved busbar filter is proposed and fabricated. Experimental results show a significant improvement on busbar filter attenuation.
