Abstract

In this paper, common issues associated with incorporation of an inline filter cable, also know as `can´ filter are investigated. In the analysis presented, it is shown that impedance interactions resulting from the integration can significantly affect the overall performance of the power supply often resulting in non-compliance to regulatory emissions requirements for the supply.
