| Abstract |
Two novel modulation schemes are proposed for three-phase ACAC
Sparse Matrix Converters (SMC) which facilitate the formation of
reactive input current for purely reactive load or purely active load and
operation at the modulation limit. The derivation of the modulation schemes
which also could be employed for Conventional Matrix Converters and rely
on a decoupling of the output voltage and the input current formation is
described in detail. Furthermore, the operating limits, i.e. the maximum
reactive input current which could be formed for given modulation index
and load current amplitude are determined. Finally, all theoretical
considerations are verified by digital simulations of a 7.5kW Very Sparse
Matrix Converter. |
