Patent ID: 7923960

Claim:
Method of controlling a power bridge ( 1 ) intended to control an electrical load ( 3 ) comprising several phases, the power bridge ( 1 ) being intended to be connected to the electrical load ( 3 ) via several arms (B 1 , . . . , B 3 ), at least one per phase, and being intended to be controlled by switching functions (SC 1 , SC 2 , SC 3 ), the said switching functions determining control vectors ({right arrow over (V 0 )}, . . . , {right arrow over (V 7 )}) for controlling the load, the said control vectors ({right arrow over (V 0 )}, . . . , {right arrow over (V 7 )}) being subdivided into freewheeling control vectors ({right arrow over (V 0 )}, {right arrow over (V 7 )}), and active control vectors ({right arrow over (V 1 )}, . . . , {right arrow over (V 6 )}), the said method comprising the application of a method of producing switching functions that produces a reduced number of combinations of switching functions corresponding to freewheeling control vectors ({right arrow over (V 0 )}, {right arrow over (V 7 )}) in order to produce a succession of control vectors, characterised in that said method of producing switching functions comprises a step of selecting at least two bridge arms able to be inhibited according to an order relationship and a step of inhibiting, throughout the chopping period (Ts) of the power bridge ( 1 ), one of the said at least two bridge arms able to be inhibited.
