Abstract

A differential power processing (DPP) isolated-port photovoltaic (PV) architecture based on dual active bridge submodule integrated converters (subMICs) is designed to improve the energy capture efficiency of a PV system in the presence of mismatch conditions. To facilitate the control design, a small-signal model of the DPP PV architecture is developed in this work based on the discrete-time modeling method. Discrete compensator for the subMICs is designed accordingly. The validity of the modeling and control is verified by experimental results.
