Abstract :
Based on a short summary of the theoretical basics of the
zero-ripple current phenomenon a special zero input current
ripple boost converter topology as presented in the literature is
investigated. It is shown that the complete suppression of the
input current ripple of the system is only given in a theoretical
extreme case. For a practical realization only such a ripple
reduction of the input current of the basic converter structure
is obtained as corresponds to a simple low-pass input filter.
This is proven by a detailed analysis also for a zero-ripple Cuk
and for a zero-ripple SEPIC converter structure. Furthermore, it
is shown that the realization of a zero-ripple Cuk or zero-ripple
SEPIC converter is not linked to a magnetic coupling of the input
and output inductors, but can also be achieved by a simple
rearrangement of the elements of the basic converter structures.
There one can see that the operating behavior of a zero input
current ripple SEPIC converter is equivalent to the operating
behavior of a buck-boost converter stage with LC input filter.
Finally, the advantages and disadvantages of the different
realization approaches of zero-ripple topologies are compared.
Also, an outlook towards the planned further treatment of the
topic is given.
