PROCEDE DE COMMANDE ET DE CONTROLE D'UN ELECTRO-AIMANT, NOTAMMENT DANS UN DISPOSITIF DE COMMANDE DE SOUPAPE A LEVEE VARIABLE

摘要

Disclosed is a control and monitoring method via H bridge of an electromagnet including a solenoid through which a current can be passed in one direction and in the opposite direction. The solenoid delivers a signal corresponding to a mechanical locking movement. Once a current flows in the solenoid, the bridge switches automatically into high impedance with all transistors thereof blocked. A measurement is then taken at the terminals of the solenoid to verify the locked state of the electromechanical system.
