| Abstract |
In the ambit of the steady state control techniques for inverters, despite its conceptual
validity the harmonic elimination concept is scarcely employed due to the difficulties involved in
the actual determination of the solution for the classic methods applying it. In fact, for these
methods the solution can be obtained only in approximated way, and separately per each case
considered, by mean of iterative numerical algorithms requiring a not negligible computational
effort. The application of the same base concept to the zeroing of entire harmonic families, rather
than single components, allows instead to conceptually overcome the above problems: in fact,
despite the greater complexity of this formulation, it results theoretically possible to translate the
problem into a suitable system of simple linear algebraic homogeneous equations, that can be so
easily exactly solved at least in ideal terms. This paper presents the theoretical treatment of the
general harmonic families elimination problem by mean of structural properties, including
application considerations and a numerical example. |
