摘要：

The main goal of this paper is to design and analyze a bidirectional floating interleaved DC-DC buck-boost converter applied to a residential photovoltaic (PV) power system with energy storage. The floating interleaved bidirectional converter produces a higher DC voltage gain compared to conventional converters, reducing the required number of series connections for the PV and battery modules. This paper provides a small-signal model of this bidirectional DC-DC converter, and describes control strategies for the DC-DC and DC-AC converters applied in a typical residential PV power system. The papers shows a transitional control strategy from grid-connected to islanded operating modes, as well as the back connection with the boost/buck operating modes for the bidirectional DC-DC converter. The paper describes the DC link management and voltage control where the regulation techniques are demonstrated by analysis and simulation results showing a complete system operation. Experimental results validate the proposed inverter control scheme.
