Abstract :
This paper is aimed at the design of soft-switched flyback DC-DC converters taking into account conducted and radiated emission noise aspects. In fact, by a proper system design, the use of an active voltage clamp in flyback converters may result in reduced voltage stresses, soft switching of the main devices, and improved EMI. The paper discusses different design aspects and their impact on the generated noise. Theoretical results are confirmed by experimental measurements
