Implementation and design of an interleaved Cuk converter with selective input current ripple elimination capability

Abstract

Nowadays, buck-boost DC-DC converters are widely used in numerous power devices. However, to have a suitable buck-boost DC-DC converter, reducing the input current ripple seems to be necessary. Also, having a lower current ripple at the converter output allows using low-cost, long-life ceramic capacitors instead of electrolytic capacitors. The presented buck-boost converter is made by interleaving two Cuk converters with positive and negative output voltage polarity, which provides the chance to eliminate the input current ripple at the selective duty cycle. The selective duty ratio can be determined by designing the inductors amounts at the input side of both converters. Though a new combination for the buck-boost converter is presented, which has zero input current ripple and low output current ripple which is obtained by output inductors. The converter maximum voltage gain is 2D/1-D and has easy control. In conclusion, a prototype model with 100-W output power is implemented, and the theoretical analysis and laboratory results are compared and validated.

Double-Dual DC-DC Conversion: A Survey of Contributions, Generalization, and Systematic Generation of New Topologies

“…Therefore, the gains for the single and DD SEPIC converters are (11) and (12), respectively. [23], which is derived from the traditional Ćuk converter with the systematic procedure discussed in Section II.…”

“…Fig.12(a) shows the traditional Ćuk converter, while Fig.12(b) shows the DD Ćuk converter[23], which is derived from the traditional Ćuk converter with the systematic procedure discussed in Section II.As expected, all capacitors and input voltage sources are in additive series; however, the polarity of the output voltage in each individual switching stage is in the opposite direction compared to the SEPIC converter. Therefore, the gains for the single and DD Ćuk converters are, respectively,…”

“…3(d) is drawn in a planar way, which does not affect the circuit's operation. In addition to DDBC, several topologies with the double dual interconnection have been recently introduced to the literature [20]- [44]; this includes, for example, the buck [20], the Cuk [23], the multilevel boost [29], Fly-Back [35], the combination of converter [36]- [38], inverted double dual boost [41].

Implementation of a novel buck-boost converter based on coupled inductor for renewable energy applications

“…To solve the effect of non-common and hold on the voltage gain with previous converter, a modified SEPIC converter is proposed in Wang, et al 27 . A novel negative output buck-boost converter in Ding and Wang 28 and a converter with interleaving two CUK converters in Taghizadegan Kalantari, et al 29 are proposed, which achieve wider conversion ratio than above dual switches converter and have non-common ground structure. Converter in Hosseinpour, et al 30 proposes a dual switches converter with common ground structure.…”
