This paper begins with the review of different parasitic capacitance cancellation techniques. The effectiveness of different cancellation techniques is discussed. The critical parameters and constraints for each cancellation technique are identified. The cancellation techniques are then applied to different applications based on their characteristics. Experiments are carried out to verify the analysis.
It is difficult to suppress high-frequency common mode (CM) EMI noise in power electronics systems. CM filters are used to suppress CM noise, but their performance is greatly affected by the effectiveness of their grounding. In this paper, the grounding issues for EMI filters, such as the mutual inductance between two grounding paths are discussed. The paper then discusses and analyzes several grounding...
