Application Note: Low Leakage Medical power supplies
There is a fine line between designing a power supply to meet low leakage requirements while at the same time ensuring compliance with international standards for Electro Magnetic Interference. This paper
discusses the sources and quantifies this leakage current, and also details the impact of balancing this with the need to meet radiated and conducted emissions.
It also discusses the limiting factors that your design needs to
meet in order for it to be used in an N+1 redundant system.
