Switch-Mode Power Supply (SMPS) Emissions Filtering: Attenuation vs. Leakage Trade-Off

Leave a Comment

Designing a power system for medical devices not only requires meeting the electrical requirements for the system, but also requires understanding the relationship between the attenuation of electromagnetic interference (EMI) and the reduction of leakage currents. The power supply is typically one of the main sources for both EMI and leakage current within a medical […]
