Abstract
A system for electronically actuating valves in an engine. The system includes first and second voltage sources, and a plurality of valve actuator subsystems coupled therebetween. Each valve actuator subsystem has a valve actuator and a switch configured to selectively control application of voltage to the valve actuator to thereby selectively control energization of the valve actuator. The system also includes a dissipation switch operatively coupled with the valve actuator subsystems, the dissipation switch being selectively operable to control dissipation of energy from any of the valve actuators.
