| Abstract: | The paper setup a simulation model of traction inverter on the platform of Simulink, simulated the working process of the traction inverter. Meanwhile, the paper considered the main traction inverter electromagnetic interference sources and simulated them, got the output of amplitude value of harmonic waves as well as THD. The elements of dead-time and parasitic capacitances were added in the model to get the influence on EMC of inverters. The changes of distortion factor and frequency spectrum of harmonic in the output waves were analyzed to provide the basis of EMC filter. |
