This paper focused on the electromagnetic compatibility problem in three-phase inverter device of electric vehicle （EV） drive system, and it is about the inhibition of the system conducted interference. Used novel iGBT active gate driver with Dynamic Voltage Rise Control （DVRC）, analysed circuit control theory and short-circuit property, to build up simulation model in Saber software. With compared to the conventional gate control method, the interference suppression of system is pleasent under the DVRC of IGBT. The innovation of DVRC method is applied to the three-phase circuit, the simulated experiment shows that DVRC method exerts a significance infuluence on suppressing the transmission electromagnetic interference.
