| Abstract: | This paper introduces EMC(Electromagnetic Compatibility) standards on switching mode power supply in China and Europe. Considering the characteristics of high frequency switching mode power supply, the discussion stresses on the design of electromagnetic impulse, printed circuit board of power supply and EMI (Electromagnetic Interference) power supply filter, as well as the EMI suppression methods such as shielding and etc. By taking these measures, the high frequency switching mode power supply is ensured to meet the requirements of CISP22 B standard. |
