摘要：

In this paper, the reaction of Voltage Source Converters (VSC) to short-circuit fault conditions across the DC terminals is analyzed. Multiple stages of the fault are identified, with the equivalent circuits generated, and analytical expressions for all voltages and currents of interest at each stage derived. The analyses presented provide detailed characterization of the converter circuit under this condition, including the effects of various circuit parameters on the fault response. The findings are validated against simulations, as well as experimentally using a single-channel replica of a dual-channel 100kW rated motor drive designed and built for aerospace application.
