中文摘要	燃料电池混合动力汽车中的驱动系统是此类车辆上主要传导性骚扰源之一,其产生高频骚扰的主要原因是逆变器内部IGBT开断过程引起很大的电压电流变化。为了研究IGBT引起的电磁骚扰机理,建立了同时包括逆变器开关管动作引起的时变参数模型和集肤效应引起的电缆电机系统的频变参数模型的驱动系统高频参数模型。针对实际的燃料电池客车,应用矢量匹配法使有理式近似拟合电缆电机系统的复杂频变参数,再折算到时域,从而在时域电路求解中同时考虑这两类复杂参数的作用,计算效率大为提高,并为实测结果所验证。; Fuel cell vehicles have shown their advantages in clean run and high efficiency compared with the traditional internal combustion engine vehicles,but they would cause more serious EMC(Electromagnetic Compatibility) problems.So the EMC research about these new kinds of vehicles is being focused on.It is verified that the driving system on the fuel cell vehicle could generate high frequency disturbance for the switching of the IGBTs(Insulated gate bipolar transistors).This is one of the main conducted disturbances in fuel cell vehicle.High frequency circuit model of driving system is a very effective tool to research the transient response,which could help to reduce the related disturbance effect.This kind of model should include the time-variable parameters caused by the switching of the IGBTs and the frequency-variable parameters caused by the skin effect of the cables and the AC motor.In this paper,the fuel cell model and IGBTs model are set up based on the other's work.The frequency-variable parameters of the cables and the AC motor are measured on the real fuel cell bus.The vector fitting method is applied to fit the complex frequencyvariable parameters into rational form which could be transmitted into time-domain easily by convolution.Then the time-variable parameters and the frequency-variable parameters could be considered together in time domain.One advantage of this method is that it could avoid calculating a lot of frequency point as necessary in frequency domain method.Another is that it could be extended to consider more complex time-variable parameters of IGBTs.This method can save a lot of calculation time.The transient response is analyzed when one bridge of the inverter is switching.Simulation results fit well with the experimental data and this method is proved to be effective.
