Ground Fault Location and Severity Estimation Method for DC/DC Converters

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
A method for detection, location and severity estimation of ground faults for DC/DC converters has been designed. The method consists in analysing the voltage signal of a grounding resistor that connects the neutral point of the system—which can be the AC neutral point of the star of the main power transformer or an artificial DC midpoint—and ground ...
