Abstract
Renewable energy sources like photovoltaic (PV) panels and battery energy storage are usually connected to the DC microgrids through dedicated full power DC/DC converters. Alternative to the conventional solutions is partial power converter (PPC) technology, where only a fraction of energy flow is handled by a DC/DC converter, and most of the energy flows from its source to a DC grid directly. PPC has several advantages over traditional full power converters: low power losses, lower cost, and higher power density. The proposed current-fed isolated full bridge buck-boost topology has shown excellent characteristics in PPC configuration, interfacing such nonlinear energy sources as PV panels. For experimental verification of PV partial power interface converter into a 350 V DC microgrid a 3.3 kW laboratory prototype with current-fed isolated full bridge buck-boost topology was designed, built, and tested. Experiments have proven the feasibility and benefits of PPC converter with proposed topology in DC microgrids.
