How can power converters be designed to minimize EMI?
Switch-mode power converters are highly efficient and cost-effective devices. However, they must be carefully designed and integrated into systems to avoid electromagnetic interference (EMI) problems. This article reviews some EMI sources in power converters and examines a few design considerations for DC-DC converters and DC-AC inverters in power conversion, renewable energy, and motor drive applications.
