Abstract
The hybrid partial power processing system includes differential power processing converters DPPs having low power ratings, which are used to exchange differential power between two adjacent PV modules, or between PV modules and a line capacitor (C) connected in series within the same string. The exchange of differential power by DPPs is needed to track the maximum power point of each PV module in the string. The DC power optimizing converter (DC-PO) is a DC/DC power converter used to feed current (power) from a PV module to C. The DC-PO is driven to track the maximum power point (MPP) of one PV module, and the MPP of each one of the remaining PV modules in the string is tracked by a DPP.
