The
general structures of Star Student
Project systems are depicting the series configuration and the parallel
configuration, respectively. In the series configuration the outputs of
individual interfacing converters are connected in series. Thus, the dc-link voltage
is distributed between the converter output terminals according to power levels.
In the Star Student Project parallel
output terminals of the interfacing converters are connected directly to the dc
link (i.e., the input of a inverter). Each converter has to endure full dc-link
voltage at the output terminal, which requires specific solutions to meet the
high conversion ratio.
