Abstract

This paper proposes two ultra-fast short circuit
protection methods based on stray inductance in a three-phase
inverter consisting of GaN switches. The first method is called
Stray Voltage Capture (SVC), based on the voltage dip on the
inverter due to the presence of the stray inductance between
the inverter and the DC-Link capacitor. The second method
is called Stray Field Capture (SFC), based on a magnetically
coupled circuit to capture a part of the changing magnetic field
during a short circuit event. Both results in ultra-fast short circuit
protection in less than 100 ns, which is a promising solution
against the Single-Event Burnout failure type occurence.
