| Abstract: | This paper first discusses how to build circuit model for the conducted EMI coupling paths in switch mode power supply. Based on the model, its sensitivity of a switch mode power supply has been analyzed by the OrCAD/PSpice software. Simulation and experimental results show that, building appropriate circuit and then analyzing the sensitivity by computer software, we can systemically analyze how each component takes effect on conducted EMI. This technique can bring effective guides to the designing and debugging of EMC of switch mode power supply. |
