  • Patent number: 6472850
    Abstract: A method for dynamically determining tap position in a step voltage regulator is disclosed. A present tap position is determined and the value of an applied voltage across a tap changing mechanism is measured. Based upon the value of the applied voltage, a directional change in the tap position is detected. A trigger signal is also generated which is responsive to a detected change in tap position. Finally, a new tap position is calculated based upon the present tap position and the directional change in the tap position, when the trigger signal indicates that a change in tap position has taken place.
    Type: Grant
