摘要： An electrical converter (10) comprising a plurality of semiconductor switches (16), wherein the electrical converter is adapted for generating a two-level or multi-level output voltage from an input voltage by switching the plurality of semiconductor switches (16).
A method for controlling the electrical converter (10) comprises the steps of: receiving a reference electrical quantity ( i S * ) and an actual electrical quantity (i S ); determining a sequence of future electrical quantities of the electrical converter (10) from the actual electrical quantity; determining a maximal cost value based on the sequence of future electrical quantities; iteratively determining an optimal switching sequence for the electrical converter (10), wherein a switching sequence comprises a sequence of future switching states for the semiconductor switches of the electrical converter; and selecting the first switching state of the optimal switching sequence as the next switching state ( u ) to be applied to the semiconductor switches (16) of the electrical converter (10).
The optimal switching sequence is iteratively determined by: extending a switching sequence by appending a possible switching state to the switching sequence; determining a cost value for the extended switching sequence with a cost function based on the sequence of future electrical quantities; and discarding the extended switching sequence, when the cost value is higher than the maximal cost value.

摘要： A system may include a drive driving a machine. The machine may include a stator having different winding locations distributed evenly across its surface, and a number of coils arranged symmetrically among the winding locations and connected to form N sets of multiple (M) phase windings. For each winding, each corresponding coil may span a single pole to form a full pitch winding. Each winding may be offset with respect to each other to reduce a harmonic content of a magnetic flux within certain frequency range during operation. The drive may include a processing stage that includes N independent modules corresponding to each winding. Each of the N modules may have M output ports for connection to each corresponding winding. Each of the N modules may be powered by a direct current power source, and have an M number of switch matrices that have at least three levels of output.
