ABSTRACT:
An apparatus and method for load voltage compensation. This involves increasing the length of time voltage is applied to electrical components, e.g., solenoid valves, in direct proportion to the number of electrical components electrically activated to compensate for the voltage loss in the control wires leading to the electrical components. The area of compensated pulse is then equal to the area of uncompensated pulse in order to compensate for the voltage drop. The load is anticipated prior to voltage application by summing the number of electrical components and associated loads selected and applying voltage for a period of time directly proportional thereto.
