The life of ELMG Digital Power Engineers

Wednesday, May 4th, 2022

This is the life of ELMG Digital Power Engineers working for our global customers. So five years ago I was biking around Berlin after having spent the week with my ELMG Digital Power colleague and our customers and their customers, testing 12MW grid-connected power converters where the control did not yet quite work properly.

This is the Reichstag in the background. It was a beautiful, cool, Berlin day.

Eventually, the power converters worked really well and we eventually did the first commissioning for them when they were installed on the Qatar Metro Rail.

To address the issues we changed the software we had written and the FPGA code. This was to ensure that the gate pulses were always absolutely consistently in the right place at the right time. This is the constant challenge of power electronics. At 12MW it is very noticeable when gate pulses aren’t always in the right place.

ELMG Digital Power worked on a large-scale converter project, biked around Berlin on a day off, tested further in Japan, Turin, and Prague, and then commissioned the converters in Doha. As a result, our customer is now the leader in their market segment.

Working for our global customers’ success – this is the life of ELMG Digital Power Engineers.

This is one of many successful ELMG Digital Power Electronics engineering developments.
