Design and Implementation of a New Cuk-Based Step-Up DC–DC Converter

Abstract: This study proposes a novel modified Cuk converter. The proposed converter attempts to resolve the limitations of the conventional converters, such as voltage gain limitations of a canonical Cuk converter. Therefore, the mentioned improvement has made the proposed converters more compatible for renewable energy applications. Moreover, the increase of the voltage gain in the proposed converter has not impacted the efficiency or the voltage stress of the switches, which is common in other voltage boosting techni… Show more

“…The suggested converter's circuit topology includes DC input voltage Vin, the primary switch S, coupled-inductor Np and Ns, a clamp diode D1, a clamp capacitor C1, two diodes D2 and D3, an output diode Do, and an output capacitor Co. Capacitors can be parallel-charged and series-discharged to achieve high step-up gain, according to the switched-capacitor technique in [3]. The primary working concept is that when the switch is flipped on, the connected inductor induces a voltage on the secondary side and the magnetic inductor Lm is charged by Vin.…”

“…Although buck, boost, buck-boost, and Ćuk converters were briefly revised, the present paper focuses on the buck-boost concept. As a matter of fact, Ćuk converters are of higher order compared to the other concepts [25], so a straightforward extension of the proposed method to control Ćuk converters would not be realistic.…”

“…In such scenarios, a converter with an inverted output voltage is imperative. Converters such as the Cuk and the buck-boost converters are particularly favoured in these applications because they produce an inverted output voltage, as emphasized in reference [38][39][40] .…”
