Analysis of the Human Electromagnetic Exposure about the DC Bus of A Vehicle High-Voltage Electric Powertrain System
摘要
Abstract
With the development of electronic information technology and new energy technology,electric vehi-cles have become an important part of the transportation field by virtue of their advantages of low noise,zero emission and high energy efficiency.Due to the limitation of the space inside the vehicle,the distance between the occupants and the high-voltage power equipment is relatively close,and the electromagnetic energy generated by the radiation emission of the high-voltage electric powertrain system may have a certain impact on the occupants or even damage.In view of the influence of DC bus of vehicle high-voltage electric powertrain system on occupant's electromagnetic exposure,the radiation emission mechanism of DC bus in 1~1 000 MHz band is explored.Electrical parameters of different tissues of human body are calculated according to Cole-Cole model,and occupant human body models are established and simulated.The simulation results show that under the normal working conditions of electric vehicles,the electric field intensity and magnetic field intensity generated by the DC bus of the vehicle high-voltage electric powertrain system are less than the relevant standard limits,and the average specific absorptivity ratio of the whole body and the local maximum specific absorptivity ratio of the occupant are also within the standard limits.Therefore,the radiation emission generated by the DC bus of the vehicle high-voltage electric powertrain system will not cause harm to the human health of the occupants in the frequency band of 1~1 000 MHz.关键词
