磁场耦合是因为传导电流(conduction current)的电生磁效应而产生。我们需要信号从设计路径流通,但是外部环境所导致的寄生电感对电流提供了一个比原来路径较低阻抗的路径。 二、磁场耦合的产生 图1表示在一个PCB上的两个过孔,这两个过孔穿过上层散热鳍片 ...
PREVIOUS work on the gassing properties of insulating liquids revealed beneficial effects of some organic additives on gassing rate of these liquids 1. The results presented here show that these ...
IT has been previously 1,2 reported that the pre-breakdown conduction current pulses in liquid dielectrics are very sensitive to test conditions and the composition of the test liquid. It has been ...
A new technical paper titled “Resistive Switching and Current Conduction Mechanisms in Hexagonal Boron Nitride Threshold Memristors with Nickel Electrodes” was published by researchers at RWTH Aachen ...
Many systems require a power multiplexer to select between two different power sources. For example, a PCI-based board needs to be able to select between Scot Lester, Applications Engineer, Portable ...
