Resumo(s)
Bipolar DC microgrids are now starting to
become an interesting solution for power distribution.
Although presenting several advantages over DC unipolar
microgrids, bipolar DC has the intrinsic problem of voltage
unbalance that may appear depending on the converter
topology and load sharing. Therefore, this paper presents a
new DC-DC converter topology that can be used with
renewable energy sources and has the capability to
simultaneously ensure the bipolar microgrid voltage balance.
The operation of the proposed topology together with its
characteristics is described. A theoretical study of this
converter will also be presented, complemented by a set of
results from computer simulations. To support these
simulations, results from a laboratory prototype will also be
displayed. The voltage balance capability of the converter will
be checked experimentally.
