  • Power supply with load-transient anticipation
    Patent number: 4425612
    Abstract: The varying loads to which a power supply is subjected are anticipated before being placed across the power supply output by deriving device selection, direction of load change, and timing data from the control data transmitted to the load. The "on" and "off" times of the power transformer primary switch in a switching regulator power supply are adjusted for optimum power supply response to the changed load. The calculations and adjustment are made before any load change has occurred and the proper control signals to the switching regulator power supply are applied prior to or simultaneous with the load change.
