Title (EN) SYSTEM AND METHODS FOR OPERATING A SOLENOID VALVE
(FR) SYSTÈME ET MÉTHODES POUR FAIRE FONCTIONNER UNE ÉLECTROVANNE
Abstract:
(EN) A drive circuit for controlling a solenoid valve having a solenoid coil (308) and a poppet that translates therein is provided. The drive circuit includes a first node (402), a second node (404), a control circuit, and a flyback circuit (406). The first node (402) is configured to be energized by a power source to a first voltage. The control circuit is coupled to the first and second nodes (402, 404), and is configured to: (1) selectively couple the first and second nodes (402, 404) in series with the solenoid coil (308), and periodically energize the solenoid coil (308) using a pulse-width-modulated (PWM) signal having a frequency and a duty cycle configured to regulate a current conducted through the solenoid coil. The flyback circuit (406) is coupled to the solenoid coil (308) and configured to energize the second node (404) to a second voltage with energy stored in the solenoid coil (308).
(FR) L'invention concerne un circuit d'entraînement pour contrôler une électrovanne ayant une bobine de solénoïde (308) et un clapet qui se translate à l'intérieur de celle-ci. Le circuit d'entraînement comprend un premier nœud (402), un second nœud (404), un circuit de commande et un circuit de retour (406). Le premier nœud (402) est configuré pour être excité par une source d'alimentation à une première tension. Le circuit de commande est couplé aux premier et second nœuds (402, 404), et est configuré pour : (1) coupler sélectivement les premier et second nœuds (402, 404) en série avec la bobine de solénoïde (308), et exciter périodiquement la bobine de solénoïde (308) à l'aide d'un signal modulé en largeur d'impulsion (PWM) ayant une fréquence et un cycle d'utilisation configuré pour réguler un courant conduit à travers la bobine de solénoïde. Le circuit de retour (406) est couplé à la bobine de solénoïde (308) et configuré pour exciter le second nœud (404) à une seconde tension avec de l'énergie stockée dans la bobine de solénoïde (308).
