    LVQ学习矢量化算法源程序 This directory contains code implementing the Learning vector quantization network. Source code may be found in LVQ.CPP. Sample training data is found in LVQ1.Pat. Sample test data is found in LVQTEST1.TST and LVQTEST2.TST. The LVQ program accepts input consisting of vectors and calculates the LVQ network weights. If a test set is specified, the winning neuron (class) for each neuron is identified and the Euclidean distance between the Pattern and each neuron is reported. Output is directed to the screen.

  • IGBT基本参数详解

    1,Vs:集射极阻断电压在可使用的结温范围内,栅极和发射极短路状况下,集射极最高电压。手册里一般为25℃下的数据,随着结温的降低,VcEs会逐渐降低。由于模块内外部的杂散电感,IGBT在关断时Vcs最容易超过限值2,Poat:最大允许功耗在25℃时,IGBT开关的最大允许功率损耗,即通过结到壳的热帆所允许的最大耗散功Pat =(Ty-T)/Rtaie其中,Ty为结温, 为环境温度。二极管的最大功耗可以用同样的公式获得。在这里,顺便解释下这几个热阻,Rtice 结到壳的热阻抗,乘以发热量获得结与克的温差;Rthig芯片热源到周围空气的总热阻抗,乘以发热量获得器件温升;Rehb芯片结与PCB间的热阻抗,乘以单板散热量获得与单板的温差。
