Abstract: A method is disclosed for controlling at least four switching components of a multi-level converter. The method comprises receiving first and second control signals for controlling a dual-level inverter having two switching components, and processing the first and second received control signals to produce at least four switching component control signals for controlling the switching components of a multi-level converter. Also disclosed are a control logic system, a multi-level converter system and a computer readable medium.

Abstract: A method comprises: applying control signals to an inverter switching network according to a selected switching sequence, wherein a switching sequence is applied corresponding to a desired sector of a switching scheme in which a demand vector is currently located, the switching scheme corresponding to the demand vector in a space vector modulation scheme having stationary active vectors around the periphery and a stationary zero vector at an origin; storing a plurality of simultaneous switching schemes in which, for a single switching cycle, a switch in each of at least two phases of the inverter switching network is switched simultaneously from a first state to a second state with a corresponding switch in at least one other phase of the inverter switching network being in a given state and in which the switch in each of the at least two phases is switched simultaneously from the second state to the first state with the switch in the at least one other phase being in the given state; and applying a simultaneous switching sequence by applying a first of the simultaneous switching schemes in dependence on the position of the demand vector in relation to the stationary active vectors.
