Abstract

Direct current (DC) grids offer high potential in industrial applications, as they provide advantages in terms of material and energy efficiency compared to conventional alternating current (AC) grids. However, the design of such grids remains challenging due to the lack of available components and standards. This paper addresses operational stability issues in auxiliary power supplies, which are ideally derived from the main voltage level via buck converters. Using the example of the non-coverable inrush current of an air compressor, a simple and cost-effective concept for peak load reduction is presented and experimentally validated. Batteries and supercapacitors are investigated as storage technologies and compared based on the resulting current profiles. The results demonstrate that both technologies are capable of significantly reducing inrush peaks. Furthermore, the proposed concept can be directly transferred to other loads and can also be applied in combination with power supplies. Finally, recommendations for system design as well as perspectives for further development towards an industrially applicable peak load reduction system are presented.
