Micromagnetics is a field in physics that deals with the behaviour of magnetics at a sub-micrometer dimension. This theory is based on the assumption that the length of the magnetization
To model the motion of the magnetization in the time domain, the Landau-Lifshitz (LL) equation is used. It describes the evolution in time of the magnetization in a solid.
The first world war (WWI) started in august 2014, and the German army proceeded very fast through Belgium. This rapid progression created a problem in the cities that were already
Physics has always been an interesting topic, but it was during a span of only 50 years that physics completely changed the world. The movie “Oppenheimer” showed in great detail
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
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
For decades, the PID control system has stood as one of the industry’s most established and widely adopted strategies, owing to its straightforward yet efficient algorithm. Within this article, we’ll
Rule-based PID tuning methods asssume that there is a system response that can be put into an easy mathematical description. The characteristics of this response can be derived from experiments
In this article we take a closer look at the three phase power system. I will begin with giving you an overview of the differences between the two types of
Motors are primarily categorized as either AC or DC, with further classifcation based on their inherent rotation characteristics. In this article, we will commence by explaining the operation of the
