Fixing electromagnetic interference (EMI) in systems employing high-frequency DC-DC converters poses 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 systems that meet stringent EMI standards in the presence of high-frequency DC-DC converters.
