电流测量：逆变器电路的电流检测方法电机驱动用的逆变器电路使用经整流过的直流电源。如图1所示，图1连接电机的三相装有向各个桥臂供电的电力器件（这里是IGBT）。根据采用的直流电压及电流，电力器件有所...

詹姆斯韦伯望远镜（JWST）的图出了，实在惊艳，但是国内科技媒体都把重点关注在望远镜镜体、光学、摄影技术上面了，对红外传感器的文章非常少，我特地上NASA的官网查了一下，感觉又收获了不少红外技...

半导体特性分析仪主要用于对分立半导体器件进行直流特性表征，给器件的各个端口施加可编程的电压/电流并测量电流/电压，以提取各项特性参数，进行拟合与SPICE建模（可以参考Sedra and Smith）...
