Abstract This paper focuses on the control of  power flow management system for photovoltaic (PV) applications with a high efficiency bi-directional converter.. The proposed PV system involves a power source (PV array), a power sink (load), and  power sources/sink (battery), and hence, a power flow management system is required to balance the power flow among these sources. One such system is developed for selecting the operating modes of the battery by sensing the dc link voltage.  The bidirectional converter includes fewer switches, has less conduction and switching losses. The viability of the scheme has been ascertained by performing experimental studies on a laboratory proto-type.

Keywords— Bidirectional converter; photovoltaic; power flow management system; DC link voltage
