Abstract
A fast shut-off solenoid circuit network includes a solenoid circuit and a current dissipation circuit. The solenoid circuit is operable in response to an electrical current, and configured to operate in an enable mode and a disable mode. The current dissipation circuit is configured to dissipate the current discharged from the solenoid circuit in response to invoking the disable mode. The fast shut-off solenoid circuit network further includes a dissipation bypass circuit. The dissipation bypass circuit is configured to divert the current discharged by the solenoid circuit away from current dissipation circuit when operating in the enable mode.

A fast shut-off solenoid circuit network comprising:
- a solenoid circuit operable in response to an electrical current, and configured to operate in an enable mode and a disable mode;
- a current dissipation circuit configured to dissipate the current discharged from the solenoid circuit in response to invoking the disable mode;
- and
- a dissipation bypass circuit configured to divert the current discharged by the solenoid circuit away from the current dissipation circuit when operating in the enable mode.
A method of dissipating energy stored in a solenoid circuit, the method comprising:
- delivering electrical current to a solenoid circuit that is configured to operate in an enable mode and a disable mode;
- dissipating the current discharged from the solenoid circuit, via a current dissipation circuit, in response to invoking the disable mode;
- and
- diverting the current discharged from the solenoid circuit away from the current dissipation circuit, via a dissipation bypass circuit, when operating in the enable mode.
