The attenuation characteristic of on board EMI filter may be deteriorated greatly by the stray magnetic field produced by main circuit of switched mode power supply. In this paper, the magnetic coupling effect between a PFC inductor and an EMI common mode inductor is studied by experiments after analyzing the stray magnetic field distribution characteristic of PFC inductor and the sensitivity of common mode inductor. A differential mode EMI model of this PFC converter is built up, which… CONTINUE READING
