Modeling of Switching Transients for Frequency-Domain CM EMI Analysis in Double Sided Cooling Power Modules
This paper provides detailed models and analysis of the impact of parasitic capacitances on CM EMI performance in the double sided cooling (DSC) power modules. The effect of parasitic capacitances on CM EMI in DSC modules are analyzed first. Then, small-signal models for different switching stages are established to better understand the mechanisms from the perspective of interference source. Finally, based on the above analysis, several design guidance of the DSC module is given for better CM EMI performance. Moreover, an optimized DSC module integrated with a capacitor is proposed. Simulation results show that the optimized module can achieve a maximum reduction of 13 dBμV in CM EMI.
