Control of an electromagnetic actuated valve provides control of voltage to avoid inductive disturbance effects

摘要

The electromagnetic valve actuator (100) has a coil (110) coupled to a power supply (115). A second connection (300) is made to a controller (200). The coil connects with a diode (130) and a Zener diode (120). The controller has a switching stage (210) operated by the control input (205).
