Abstract
A method for increasing the power extraction capability out of Differential Power Processor (DPP) system, which consists of a chain of N serially connected PV elements and an array of N−1 gyrator-type converters which are current sourcing resonant Switched Capacitor Converters (SCCs), each of which being connected in parallel with two adjacent PV elements. Accordingly, local MPPT is continuously performed, by each gyrator-type converter, to one of its two connected PV elements by sinking or sourcing current to/from the neighboring PV element. Whenever a mismatch in the MPPs is detected, the gyrator-type converters are used to provide the difference in current that is required for each of the PV elements to operate at its MPP, such that the amount of power processed by each gyrator-type converter in the chain is linearly proportional to its location in the chain, with respect to the mismatched PV element.
