Claim Text:
1. A method for determining a photovoltaic (PV) current from each of a plurality of PV elements arranged in a differential network, the method comprising: controlling the differential network with a plurality of control signals, wherein the differential network includes a plurality of inductors, and wherein each control signal has a duty cycle; receiving a plurality of controller parameters from a the plurality of differential controllers; and calculating the PV current for each of the plurality of PV elements from a the plurality of inductor currents and the duty cycle for each control signal wherein the step of calculating further comprises multiplying an input vector by a matrix so as to generate an output vector, wherein the input vector includes the plurality of digital inductor current measurements, and wherein matrix includes matrix elements corresponding to the duty cycle for each control signal used to control the differential network, and wherein the output vector includes the plurality of PV currents.
