This paper presents the modeling, analysis,
design, and control of non-isolated boost three-port converter
(TPC). In contrast to conventional converters that suffer from
low efficiency as a result of multiple power stage conversions,
the single-inductor TPC studied here has only single stage
conversion between any two of the converter three ports.
However, the TPC dynamic analysis are complicated due to
the different energy management modes of operation. In this
paper the non-isolated DC-DC boost TPC is studied in details.
The converter components design and dynamic modeling are
presented. Also, the converter switched, averaged, and small
signal dynamic model are derived. In addition, the converter
controller design for output voltage regulation and input PV
maximum power point traking are presented. The system is
simulated using Matlab/Simulink and the obtained results
show good performance for different converter modes of
operation. |
