Abstract: A method for controlling a converter for converting an n-phase AC input voltage into a DC output voltage, each phase of the AC input voltage being connected to a switch of the converter. The method includes determining the signs of j characteristic voltages (Va, Vb, Vc, Va-Vb, Vb-Vc, Va-Vc, Va+20°, Vb+20°, Vc+20°, Va?20°, Vb?20°, Vc?20°); determining a reference combination (C1-C12, C1-C18), to which the signs of j characteristic voltages (Va, Vb, Vc, Va-Vb, Vb-Vc, Va-Vc, Va+20°, Vb+20°, Vc+20°, Va?20°, Vb?20°, Vc?20°) correspond, by comparing the signs of the j characteristic voltages to data from a reference table; and (c) opening each switch for an opening time (t1, t2, t3) pre-determined according to the reference combination (C1-C12, C1-C18) identified during the determining of the reference combination.

Abstract: A voltage inverter capable of operating in the event of a short-circuit or open-circuit fault. The voltage inverter includes: a load having three phases, each phase having a first terminal and a second terminal; first and second cells each including three branches connected together in parallel, each branch including two switches connected in series and a mid-point positioned between the two switches, each first terminal of each of the phases being connected to one of the mid-points of the first cell and each second terminal of each of the phases being connected to one of the mid-points of the second cell; and a DC voltage source, the first and second cells each being connected to the DC voltage source via two electrical isolators.
