Do We Really Need a New Safety Standard?

Figure 1: IEC/EN 62368-1 is not a merge of the two standards IEC/EN 60065 and IEC/EN 60950 but a completely new one introducing a new way of working

Safety regulations have been in place for decades in the power industry and as we know only too well, all have been through lots of revisions. And although each revision has made them more stringent and tailored to our businesses, we have become familiar with designing products to conform to latest versions. So

Silicon Carbide more Efficient than Silicon as Semiconductor

At the interface between silicon dioxide and silicon carbide, irregular clusters of carbon rings occur, which disturb the electronic function.

In power electronics, semiconductors are based on the element silicon - but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon in the scientific jo
