摘要： A drive circuit may include a SUPPLY that outputs a first voltage potential, an energy storage device that outputs a second voltage potential, and a LOAD. Switches control the flow of current through the LOAD in a flow direction or in a direction opposite to the flow direction. The first or second voltage potentials can produce current.

摘要： An exemplary hydraulic system includes a digital valve operable to fluidly connect a hydraulic load to a pressure supply, and an orifice disposed in a flow path between the hydraulic load and the digital valve. A digital controller is operably connected to the digital valve. The digital controller stores a target pressure drop across the orifice and is configured to determine an actual pressure drop across the orifice and formulate a control signal based on the target pressure drop and the actual pressure drop. The controller transmits the control signal to the digital valve for controlling the operation of the valve.
