“…Another structure for the boost converter with the capability of input current ripple elimination is proposed Rosas‐Caro et al 22 Ripple cancellation is occurred in the preselected duty cycle without adding extra components to the structure. Arias‐Angulo et al 23 propose a new structure that is a combination of boost and Cuk converter that can eliminate input current ripples at a fixed duty cycle. The zero‐ripple duty cycle could be chosen by designing the input inductors with the mentioned conditions.…”

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.
