Abstract :
Core saturation instability is a condition resulting
from excess low-order harmonic ac/dc system interactions, amplified
by increasing transformer flux offset which, in turn, is driven
by the interaction between the harmonics and the converter. A
small signal analysis method has been successfully applied to efficiently
screen a variety of conditions for core saturation instability.
The screening measures have been defined in terms of the dc system
driving point impedances.
