Abstract

This paper proposes the integrated circuit (IC) within the active EMI filter (AEF). The fully-isolated feed-forward current-sense current-compensation (CSCC) structure of the AEF is also proposed to achieve the robust reliability from electromagnetic susceptibility (EMS) to the designed IC. The noise attenuation performance is analyzed, and the design guides for the proposed AEF with IC are developed. The designed IC is fabricated by TSMC 180nm BCD process. The noise attenuation performance and stability are experimentally validated by vector network analyzer (VNA) measurement.
