Power-Electronic Buck Converter Based High-Power Test Circuit for Investigating DC Switching Arcs for Battery Electric Vehicles

In this paper, an innovative test circuit based on a power-electronic buck converter is used for investigating DC arcs in a copper busbar setup. This demonstrates the capabilities of the test circuit for this use case for the first time as well as enables a deeper understanding of DC arc behavior, which is eminent for the development of adequate DC switchgear for battery electric vehicles.
