The transmission-line busbar filter is an innovative high-density electromagnetic interference (EMI) containment solution for power electronics systems. It uses the concept of the transmission-line EMI filter as a part of the power interconnection to eliminate the EMI noises in power converters. This paper presents a systematic study of the transmission-line busbar filter in a motor drive system, which includes its design, modeling, and improvement using a hybrid approach. The paper investigates the relationship between the busbar filter%26apos;s in-circuit attenuation and its geometry, and then derives a general design guideline for the transmission-line busbar EMI filters. To improve the performance of the transmission-line busbar filter, the paper proposes a hybrid busbar filter combining a transmission-line busbar filter and a one-turn inductor. This improvement provides much higher attenuation than the traditional transmission-line busbar filters. These proposed concepts have been verified experimentally not only with small-signal measurement but also with in-circuit tests in a medium-power motor drive system.
