M. Ehsani et al., POWER CONVERTERS AS NATURAL GYRATORS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 40(12), 1993, pp. 946-949
This paper presents a study based on the open-loop gyrator behavior of
a class of dc-dc converters characterized by double bridges. If the s
witching frequency of the double bridge converter is high enough with
respect to its natural frequencies, the converter can be viewed as a g
yrator from its terminals. Unlike other gyrator modeling approaches of
converters that appear in the literature, the double bridge converter
s naturally behave (open loop) as a gyrator without any extra control
circuit.
