| Abstract |
In this paper a general approach for the
determination of the line current harmonic content in
matrix converters is presented. The input disturbances, such
as voltage unbalance and voltage harmonics, are considered
as perturbations of the fundamental component, and a
small-signal analysis is used to determine the spectrum of
the line current. The proposed analytical approach has a
general validity, because it takes into account the effects of
the line and filter impedance, the supply harmonics and the
input current modulation strategy as well. Hence, it could be
usefully employed to evaluate the line current quality in the
point of common coupling for different filter topologies and
supply distortions. Experimental results are given to
confirm the analytical solution. |
