A new structure for high power integrated EMI filter was proposed based on that the traditional filter with small power is difficult to adapt to the environment of electric vehicle DC-DC converter.The integrated EMI filter can not only suppress interference effectively,but also optimize the volume of the filter and improve the power density.In addition,this paper took an appropriate method to extract parasitic capacitance and eliminate its adverse effects on the filter at high frequency.Finally,the simulation results verify this degin based on finite element method,and designed integrated EMI filter combined with the actual requirement of electric vehicle.
