Claim One:
1. A power conversion system, comprising: at least one multi-phase AC connection having two or more AC terminals for receiving or supplying multi-phase electrical power; a DC circuit for receiving or supplying DC electrical power, the DC circuit comprising first and second DC current paths and at least one storage component; a switching network comprising a plurality of switching devices individually coupled between one of the DC current paths and one of the AC terminals, the switching devices individually operable to selectively electrically couple the corresponding DC current path with the corresponding AC terminal according to a corresponding switching control signal; and a switch control system providing the switching control signals by space vector modulation according to a plurality of dwell time values derived from a modulation index and an angle associated with a current reference vector representing a desired converted AC in a current space vector diagram sector to selectively provide three switching states in the switching network corresponding to three diagram vectors defining the current diagram sector in each of a continuous series of space vector modulation periods to convert power from DC to AC or AC to DC using the switching network, the switch control system comprising a multi-sampling SVM component operative to sample the current reference vector and derive the dwell time values a plurality of times during each modulation period.
