Abstract[English]
In an aspect, there is provided a method of operating a pulse width modulation (PWM) valve for a fluid application of an agricultural implement. The method includes applying full current for a first period of time to fully open the PWM valve, applying a reduced current for a reduced current value that is from 0 up to a dissipating threshold value that is below full current for a second period of time to rapidly dissipate energy in the PWM valve that is fully open, and applying a holding current for a third period of time to hold the PWM valve fully open for the fluid application.[French]
Selon un aspect, l'invention concerne un procédé de fonctionnement d'une soupape de modulation de largeur d'impulsion (MLI) pour une application de fluide d'un outil agricole. Le procédé consiste à appliquer un courant maximal pendant une première période de temps pour ouvrir complètement la soupape MLI, appliquer un courant réduit pour une valeur de courant réduite qui va de 0 à une valeur seuil de dissipation qui est inférieure à un courant maximal pendant une deuxième période de temps pour dissiper rapidement l'énergie dans la soupape MLI qui est complètement ouverte, et appliquer un courant de maintien pendant une troisième période de temps pour maintenir la soupape MLI complètement ouverte pour l'application de fluide.
