Jul 99 – Dec 01 Corporate Research Center Germany

Reported to Project head, Department Head

ABB Corporate Research Center was located in Heidelberg in Germany which was later moved to Ladenburg. I was selected for the internal job rotation where I became employee later due to my all round skills in hardware topology and control hardware and software including simulation. Worked in the power electronics department mostly on one High Impact Project (HIP) sponsored by the CTO and Power Systems T&D. It was in the area of Distributed Generation including Power Quality and UPS like features to operate the equipment in islanding, detect islanding and connect back to grid when it is back. The work included researching the design and control methods, design hardware and software, simulate and write control software in C, build power hardware including converter, controller, loads etc and demonstrate the complete technology prototype and transfer the technology developed to the interested BU’s. That time ABB evaluated the possibility of getting in to distributed generation and UPS however differed the decisionexcept for the micro turbine project.
