Abstract
The invention is a method of tracking the overall maximum power point of a grounded bipolar photovoltaic array by tracking and regulating the voltage of the weaker of the two monopolar subarrays at any instant in time. The transfer between subarrays being tracked for the maximum power point is seamless when the voltage of one subarray becomes lower than the other. This tracking method insures stable operation and maximum power transfer under all balanced and unbalanced PV array conditions. This tracking algorithm would typically be part of a larger digital power converter control system.
