The technical PWM (Pulse Width Modulation) is used extensively in the static converter order. It has the advantage to allow the selection of harmonic to eliminate while solving a non linear equation system. The angles are calculated and memorized beforehand. In the first case it overloads the processor of as much more, that every variation of order; drag a new resolution of the equation system. In the second case it requires a capacity memory important of storage. The artificial neuron networks after training, permit to surmount the quoted risks, while nearly providing instantaneously these angles of commutation.
