| Abstract: | Based on the stray capacitances of transformer and heat-sink, analysis on the means and the features on generation of EMI by transformer and heat-sink is made, and analytical model of common mode conducted EMI emission in switch mode power supply is built; and based on this some solutions and design methods are proposed to reduce the level of common mode conducted EMI emission source in revers-stimulation type switch mode power supply, the effectiveness of each design method is verified by experiment. |
