Achieving EMI conducted emission compliance for high voltage conversion with switching frequency above 1.3MHz

Presented by Nicola Rosano, Sr. Strategic FA/System Engineer, Vicor

Fixing electromagnetic interference (EMI) in systems employing high-frequency DC-DC converters pose a critical challenge due to the intrinsic nature of these converters. High-frequency operation and compact layouts, while beneficial for compact designs and efficiency, intensifies EMI concerns. The rapid switching of currents in these converters generates harmonics that can propagate through the circuit and radiate as electromagnetic waves.

Mitigating EMI requires sophisticated filtering and shielding strategies, adding complexity to the design and increasing costs. Achieving effective EMI suppression without compromising the converter's performance requires a delicate balance, as aggressive filtering may hinder efficiency. Intricate trade-offs are required to develop a robust system that meets stringent EMI standards in the presence of high-frequency DC-DC converters.

Nicola Rosano received his B.S. degree in 2010 and his M.S. degree cum laude in 2013 in electrical engineering (EE).  He worked in the military, defense and space sectors at Thales Alenia Space and Airbus Defense and Space as well as in the automotive sector at BorgWarner and Stellantis as Sr. HW Power System Engineer. In Sept. 2022 He started working at Vicor as Sr. Strategic Application & System Engineer EMEA acting as tech focal point for automotive power systems. He has been granted a few patents, and is cultivating an analog/power electronics educational YouTube channel in collaboration with Ridley Engineering. His current research interests include power electronics, circuits and systems, electronic instrumentation, and engineering education.
