Analysis of Radiated EMI and Noise Propagation in Three-Phase Inverter System Operating Under Different Switching Patterns

In this paper, a numerical model using the finite-element (FE) method was used to predict the electromagnetic interference (EMI) generated by 325-V, 5-kW power inverter, supplying a variable three-phase load. A comparative analysis was performed to evaluate the effects of different switching pattern...

Description
Summary:In this paper, a numerical model using the finite-element (FE) method was used to predict the electromagnetic interference (EMI) generated by 325-V, 5-kW power inverter, supplying a variable three-phase load. A comparative analysis was performed to evaluate the effects of different switching patterns on the radiated and conducted EMI levels. An experimental setup was arranged to validate the simulation results. The proposed approach is suitable for prediction of radiated and conducted EMI generated by power converters. This helps reduce the post prototype EMC testing cost by minimizing redesign and modifications of final converter product.
