This study proposes a new design for a non-isolated buck converter with con-
tinuous input current. As required, the integration of additional modules into
the existing structure permits a significant decrease in the converter's gain to
attain significantly lower values. In order to create the proposed converter, the
input voltage connections to the Cuk converter were changed. In this configu-
ration, the operational state of the Cuk converter has been changed from
buck-boost to step-down by connecting the input power source's negative
polarity to the inductor's terminal. In addition, the proposed converter benefits
from a common ground between the input source and output port. Moreover,
it can achieve a significant reduction in gain by increasing the number of
series modules. Finally, the compact converter was smoothly incorporated
onto a printed circuit board (PCB) and afterward validated by an output power
of 80 watts.
