摘要 为了实现车载设备的传导噪声预估,二极管模型需在车载环境的宽温度变化范围内对动态特性进行准确描述。以PIN型功率二极管为研究对象,分析了定温度的拉式变换解析模型,引入温度参数,将原模型参数与温度的关系以函数的形式表达,实现任意结温下的模型参数温度修正,从而建立变温度的PIN二极管动态特性模型。在此基础上,通过温箱实验对感性负载条件下的功率二极管动态性能进行测试,实现了模型参数抽取和模型验证。结果显示,该模型在25~120 ℃的宽温度范围内,可实现反向恢复特性的精确模拟,各项特性参数的误差均较小,不会出现PSPICE通用模型的异常振荡问题,能满足宽频率及宽温度范围的汽车级EMI预估需求。

Abstract:In order to realize the pre-evaluation of conducted noise of on-board equipment,it is necessary for the diode model to describe the dynamic characteristic accurately at wide range of temperature within on-board environment.By choosing the PIN power diode as the research object,the constant temperature Laplace transform analytical model is firstly established.By introducing the temperature parameter,the relationship between the parameters of the origin model and the temperature is expressed as a function.Thus the temperature correction of the model parameters is realized at any junction temperature,and a temperature-variable dynamic characteristic model for PIN diode is built.On this basis,the dynamic performance of the power diode is tested with the inductive load by the temperature chamber experiment.The model parameter extraction and the model verification are also realized.It is shown that,within the temperature range from 25 ℃ to 120 ℃,this model is accurate for the reverse recovery characteristic simulation with relatively small errors,and the abnormal oscillation of the PSPICE general model no longer exists.So the on-board EMI pre-evaluation requirements of wide frequency and temperature range are satisfied.
