The number of
large-scale solar photovoltaic (pv) systems continues to increase, while the
size of the largest systems has already reached several hundred megawatts. this
trend will challenge existing pv system architectures and will require new pv
system architectures with higher power ratings and higher voltage levels at the
point of common coupling (pcc). this article reports a medium-voltage (mv) dc-bus
pv system architecture based on a high-gain soft-switched interleaved boost
(ssib) dc–dc converter. the interleaved characteristic increases the
flexibility of the converter, allowing for either a higher voltage and/or current
rating, thus increasing the power rating of the converter.
