Limit-exceeding problems exist in electric field and magnetic field emission level in a type of hybrid electric vehicles. Characteristics of main electromagnetic interference source in the vehicles are analysed, production mechanism of radiated electric filed and magnetic field in the whole vehicle is discussed and the conclusion that the main interference sources of whole vehicle electromagnetic emission are three-phase working current of drive motor and electric motor controller is cleared up. Additionally, considering the properties of interference source, corresponding suppression measures for interference are proposed and applied. In the end, comparison validations with experiments are made to show that the whole vehicle electric field in low frequency range and the level of magnetic emission can be decreased by the suppression measures applied. The measures can also provide a reference for electromagnetic compatibility improvement in other hybrid electric vehicles.
