Abstract: A solenoid drive circuit (100) includes a boost energy storage device (1) , such as a capacitor, that captures energy from and discharges energy to a solenoid (104) . Switches (Sl, S2) control the connection between the boost device (1) , the solenoid (104) , and a power source (102) . This allows the solenoid response time to be variable based on the characteristics of the boost device as well as the solenoid. By providing two different solenoid current rise and decay rates and by capturing and re-using energy stored in the solenoid, the inventive drive circuit enhances solenoid response and increases efficiency.

Abstract: An exemplary hydraulic system (10) includes a plurality of digital valves (40, 70, 86, 100) each valve fluidly connectable to a corresponding hydraulic load (26,28,30). The digitals valves are operable to fluidly connect the corresponding hydraulic load to a pressure source (12). The hydraulic system further includes a digital controller (114) operably connected to the plurality of digital valves. The digital controller is configured to assign a priority level so that it is associated with each of a plurality of hydraulic loads, and to formulate a pulse width modulated control signal based on the assigned priority levels. The digital controller transmits the control signal to the plurality of digital valves for controlling the operation of the valves.
