Tunneling effect at semiconductor/oxide interfaces
Electron tunneling is a phenomenon commonly observed at semiconductor/insulator or metal/insulator interfaces, particularly when the insulating layer is thin, typically a few nanometers thick. To grasp its intricacies, let's simplify the scenario.
What are thyristors and how do they work?
In this article I will discuss what thyristors are and how they work. I will start with the semiconductor structure of a thyristor and use the characteristic V-I curve to explain the three different modes. Subsequently, I will use an two transistor model to explain the thyristor from a different ...
3-phase IGBT-inverter – Working principles
In this article the 3-phase IGBT inverter and its functional operation are discussed. In order to realize the 3-phase output from a circuit employing dc as the input voltage, a 3-phase (IGBT) inverter has to be used. The inverter is build of switching devices, thus the way in which the ...
