N2 - This paper presents a novel control algorithm for the PV-Isolated-Port (PV-IP) photovoltaic differential power processing systems. Two levels controls are involved in this algorithm: submodule-level control and the module level. Specifically, the voltage equalization (VE) control method is used in the submodule-level converters in order to regulate each PV submodule operating on its nearly maximum power points (MPP) with easy implementation and high efficiency. For the module-level converter, the control will regulate the string current to unique optimal string current value (OSCV) so that the submodule-level DPP converter will process the minimum power reducing the power loss. The measured efficiency of the whole system reaches to 97.5% after using the designed algorithm.
