Bidirectional Power Flow Control Using Four-Switch Buck-Boost Converter in DC Power Network

抄録

In this study, we examine the use of a four-switch buck-boost converter (FSBBC) as a bidirectional power flow controller (BPFC) for flexible power flow control in DC power networks. In our previous studies, a cascaded boost-buck converter has been used as the BPFC, and few studies have been conducted using other circuit topologies. In this study, we develop a power flow control method using an FSBBC. Because an FSBBC has fewer passive elements than the conventional circuit topology, it is expected to achieve higher efficiency than the conventional circuit. We verify the effectiveness of the power flow control using an FSBBC by experiments.
