An enhanced DC-DC converter is proposed in this paper,
based on the combination of the Cuk and SEPIC converters.
This converter uses a single switching node which is common
to both Cuk and SEPIC energy transfer stages. The converter
uses only one switch, yet provides dual outputs in the form of
a bipolar DC bus with a common ground. Since the switch is
grounded, a simple, non-isolated gate driver may be used. The
proposed converter uses integrated magnetics cores to couple
the input and output inductors, which significantly reduces the
input current ripple. The new converter is referred to as the
Coupled Inductors Combined Cuk-SEPIC (CI-CCS) converter
