3D EM Simulation of a resistance spot welding gun

This article is concerned with the 3D electromagnetic modelling and equivalent circuit parameter extraction of a Resistance Spot Welding (RSW) gun. The parameters for the gun are not as easily established for the gun as for other RSW system components. The current transformer and electronic converter electrical parameters are either known or can be obtained by standard test procedures. This is not the case for the gun where the electrical parameters are unknown and difficult to measure. A 3D EM simulation using CST EM STUDIO® can be used to establish these parameters and complete the system characterisation. Read full article..

Siemens optimiert Leistungstransformatoren mit CST EM STUDIO

„CST EMS ist mittlerweile bei Siemens ein fester Bestandteil des Entwicklungsprozesses verschiedenster Leistungstransformatorkomponenten geworden, insbesondere wegen der einfachen Bedienungsoberfläche und der Vielfalt der Löser. Dank der sehr engen Zusammenarbeit mit dem CST EMS Entwicklungsteam wurden Wünsche, Anregungen und Ideen immer offen aufgegriffen und zügig umgesetzt. Dies bildet die Basis für unsere Entscheidung auch weiterhin verstärkt die von CST angebotenen Lösungen anzuwenden.“ Read full article..

3D IR-Drop simulation of a complex multilayer PCB

This article deals with the simulation of the voltage drop for complex power delivery networks. Such a simulation is useful to the design engineer in order to ensure power integrity. With the help of the CST EM STUDIO™ stationary current solver the 3D distribution of the potential and current density on all layers of a complex PCB board can be easily determined. The static IR-Drop simulation is the primary focus in this article but a dynamic simulation would also be possible in CST MICROWAVE STUDIO®. Read full article..
