Abstract


In order to improve the stability of the photovoltaic system, this paper introduces an integrated converter based on Interleaved Boost Converter and Full-bridge converter. By integrating a boost converter into a full-bridge converter, the two non-isolated input ports, which connect with the PV and Battery, are isolated from the load. This article focuses on the three-port converter principle, modeling and simulation. Finally, we fabricated a prototype of a three-port integrated converter, and verified the feasibility of the three-port converter experimentally.
