Patent ID: 8117484

Claim:
A method for generating binary signals (So 1 , So 2 , So 3 ) out-of-phase by a control phase-difference angle (φ) continuously variable with respect to at least one synchronization binary signal of a set of synchronization binary signals (Si 1 , Si 2 , Si 3 ) having the same variable period (ΔTtotal), comprising the steps of: producing rising ( 8 ) and falling ( 12 ) edges of said out-of-phase signals (So 1 , So 2 , So 3 ) by calculating at least a level-switching delay (ΔT 1 ) from at least rising synchronization edges ( 2 , 3 , 5 , 6 ) or falling synchronization edges ( 1 , 4 , 7 ) of said synchronization binary signal (Si 1 , Si 2 , Si 3 ) according to at least said control phase-difference angle (φ); measuring an interval of time (ΔTpn) between two of said successive synchronization edges ( 1 - 7 ), one being rising and the other falling; at least one reference edge ( 4 , 5 , 7 ) being chosen from said synchronization edges ( 1 - 7 ); a number of said out-of-phase signals (So 1 , So 2 , So 3 ) and a number of said synchronization signals (Si 1 , Si 2 , Si 3 ) being equal to a predetermined number of phases; said synchronization signals (Si 1 , Si 2 , Si 3 ) having a duty cycle ratio equal to 0.5 and being out-of-phase with each other by a nominal phase-difference angle (Φ) in degrees equal to 360° divided by said number of phases; and calculating said delay (ΔT 1 ) for a current synchronization binary signal (Si 1 , Si 2 , Si 3 ) among said synchronization binary signals (Si 1 , Si 2 , Si 3 ) with a view to producing the corresponding edge ( 8 , 12 ) of the associated current out-of-phase binary signal (So 1 ) by the following expression: Δ T 1 =ΔTpn *(Δφref−φ+180)* Np/ 360, where: ΔTpn is said interval of time; φ is said control phase angle between −180° and +180°; Δφref is the phase difference φ0−φr, expressed in degrees, between an initial edge of initial phase angle φ0 of said current synchronization binary signal and said reference edge ( 4 , 5 , 7 ) of reference phase angle φr of a reference synchronization binary signal chosen from the synchronization signals (Si 1 , Si 2 , Si 3 ); and Np is equal to twice the number of phases.
