Zusammenfassung:	Aspects for detecting faults in a redundant power converter are described. In an exemplary circuit aspect, a circuit for sensing faults in a redundant power converter includes a first voltage level detection mechanism and a second voltage level detection mechanism. The first voltage level detection mechanism detects a voltage level at a predetermined node relative to a first switch gate voltage during a first switch on-time. The second voltage level detection mechanism detects a voltage at the predetermined node relative to a second switch gate voltage during a second switch on-time, wherein a fault is detected when the voltage level violates a threshold level in one of the first voltage level detection mechanism and the second voltage level detection mechanism.
