Abstract :
In the design of a low cost, low weight, small size and high performance power converter, EMI design is a challenging task. The paper discuses the EMI design difference between low power and high power converters, and presents methods of passive cancellation of common mode current emission to reduce conducted EMI emissions and radiated emissions in a low power isolated converter. EMI design techniques based on near field measures are presented. A 2W flyback converter has been designed and results are experimentally verified.
