The fast voltage and current transients during switching events in an inverter are identified as one of the major sources of EMI in drive application. These transients were measured and analyzed qualitatively under various application conditions with different IGBT/Diode combinations from different manufacturers. Based on the results possible module integrated solution with passives were investigated to reduce the fast transients in the module level. The proposed solutions reduce or eliminate the effort and cost of the external EMI filter design on system level.
