Abstract
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.
