Embodiment Construction
[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] Such as figure 2 As shown, in a neural network spatial mapping modeling method for power transistors of the present invention, first, sample data for model training must be obtained. The DC input sample data is the input voltage, denoted as [v gf , V df ] T ; The DC output sample data is the output current, denoted as [i df ]. The AC input sample data is the input voltage and frequency, denoted as [v gf , V df , Freq] T ; AC output sample data is S parameter, denoted as [S 11 , S 12 , S 21 , S 22 ] T . The sample data can be obtained through actual measurement devices or simulation software.
[0034] Build as figure 1 As shown in the neural network structure, set the output mapping network structure. The output mapping network uses a 3-la...
