GVA experts are regularly in demand as authors for technical publications. And of course, we are happy to share our expert knowledge. You can find a selection of these publications here. Enjoy!
Pulse Current Systems up to 35kA
The testing of safety elements under short-circuit conditions is an important safety aspect in the development of new electric vehicles.
Essential considerations relating to partial discharge
Insulation voltage, test voltage, partial discharge and insulation strength – terms development engineers frequently have to deal with. But how are they related and which aspects and data are ultimately relevant to the developer?
Auxiliary Power Supplies for Medium and High Voltage Applications
New IGBTs and IGCTs, together with appropriate snubber and freewheeling diodes up to 5.5 kV (6.5 kV respectively), are opening up the possibility of establishing power electronics for the medium voltage level with manageable effort. Tri–level switching topologies and cascaded switching systems are the preferred architectures used here.
