Power Flow Management in Three Port Converter Using PV Panel with Maximum Power Point Tracker

This paper presents three-port DC-DC converter modeling, its simulation and its control. The three port converter interfaces with the PV panel, bidirectional battery and load which is isolated by a transformer. There are two sources used in the three-port converter and the flow of power in the converter is controlled by switches (MOSFETs) on-off states. To obtain maximum power from the PV panel, a buck-boost converter is added in front of the PV panel and a MPP tracker is used to control the buck-boost converter. The three-port converter circuit is composed of four MOSFETs which are used as switches and a transformer that provides isolation between the input and output sides. Three cases of three-port converter operation are analyzed; in the first case, PV panels feed directly the load; in the second case, the PV panels feed the load and, in same time, charge the battery; in the third case, PV panel together with battery assure the load demand.
