[Abstract]:In order to predict the conduction noise of vehicle equipment, the diode model needs to accurately describe the dynamic characteristics in the wide range of temperature variation in the vehicle environment. Taking the PIN type power diode as the research object, the analytical model of pull transformation with constant temperature is analyzed, and the temperature parameter is introduced. The relationship between the parameters of the original model and the temperature is expressed in the form of function, and the temperature correction of the model parameter under arbitrary junction temperature is realized. The dynamic characteristic model of PIN diode with variable temperature is established. On this basis, the dynamic performance of the power diode under inductive load is tested by the temperature box experiment, and the model parameter extraction and model verification are realized. The results show that the model can accurately simulate the reverse recovery characteristics in a wide temperature range of 25 鈩，
