ABSTRACT:
A voltage regulator controller includes means for determining the tap position based on regulator impedance characteristics. In a preferred embodiment, the tap position determination system is embodied as part of an regulator designed to operate within a fixed percentage range of regulation (e.g. .+-.10%) with the identical number of turns between each of its series winding taps. In this environment, the regulator tap position is determined as a function of the regulator input voltage, the regulator output voltage, the regulator series winding current, system load power factor and internal regulator impedance.
