Abstract

A short circuit detection based on a Stray Voltage Capture (SVC) cannot robustly detect a Hard Switching Fault (HSF) if an additional stray inductance is present in the short circuit path. Therefore, this paper proposes an extension of the Stray Voltage Capture (ESVC) method to detect a HSF based on the integration of the SVC output. The result shows that a HSF is detected in the MOSFET linear region and can be easily implemented in any converter with a Half-Bridge structure.
