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. […]
Mitigate reverse recovery overshoot in MOSFET body diodes
Because of their compact size, higher efficiency, and superior performance in high-power applications, SiC MOSFETs are now replacing Si devices in switching applications. SiC devices enable faster switching times, significantly reducing switching losses. These advantages stem from the unique electrical and material properties of SiC-based devices — snappy reverse recovery inherent to the structure of […]
