Dear colleagues,
I am a little confused regarding ex-certified motors connected to an inverter of any brand. As I live in Europe, I will stick to European/IEC-terms regarding this issue, but I believe that the consequenses should be more or less the same anywhere....
As far as I understand...
Dear colleagues,
I am doing some brainstorming on how to complete a VFD-system with several large inverters connected to a common dc-link and with one rectifier to supply the DC.
First thing on my mind is how to precharge the capasitors which are already in the inverters. I am, ofcourse, aware...
Dear all,
I'm very familiar with phase-shift transformers supplying for instance large VFD- or other rectifier-loads. I totally understand how and why a phase-shift of 30dgs eliminates the 5th and 7th harmonic on the primary-side on for-instance a three-winding transformer. Of course, the same...
