Abstract:
A current conversion method for an electrical device. The electrical device includes a three-phase electric motor and two three-phase inverters. Each inverter is controlled by modulation of at least six non-zero space vectors or space vector modulation. The output voltage of each inverter is given by a reference space vector. For each inverter, the method includes modulating the space vectors by a space-vectors activation sequence having at least two switching intervals in which three adjacent space vectors are used. A device to convert current and a vehicle implementing the current conversion method are provided.

Claim (Index 11):
The current conversion method according to  claim 9 , wherein, for at least one inverter, a cyclical ratio of each of the three adjacent space vectors, V i\u22121 , V i  and V i+1 , implemented on a switching interval is: \u03b1 i - 1 , x = 1 - 2 \ue89e 3 \u03c0 \ue89e M x \ue89e sin \ue8a0 ( \u03b8 x \u2032 ) , where \ue89e \ue89e \u03b8 x \u2032 = \u03b8 x - ( i - 2 ) \ue89e \u03c0 3 ( A ) \u03b1 i , x = - 1 + 6 \u03c0 \ue89e M x \ue89e sin \ue8a0 ( \u03b8 x \u2032 + \u03c0 6 ) ( B ) \u03b1 i + 1 , x = 1 - 2 \ue89e 3 \u03c0 \ue89e M x \ue89e sin \ue8a0 ( \u03b8 x \u2032 + \u03c0 3 ) ( C ) where \u03b1 i\u22121,x  is the cyclical ratio of the space vector V i\u22121 , \u03b1 i,x  is the cyclical ratio of the space vector V i , and \u03b1 i+1,x  is the cyclical ratio of the space vector V i+1 , i is a whole number between one and six, \u03b8 x  is an angle between the reference space vector and an abscissa of an orthonormal marker, x is a whole number between 1 and 2, and M x  is modulation index, a real number between 0 and 1.
