Hybrid Cuk Converter for Green Energy Applications
Deepti Prasanna Tata, R. Sripriya and N. Bhupesh Kumar

In the current century, energy consumption is tremendously rising to satisfy the worldwide needs of industries and domestic usage. The primary cause of the dioxide emissions, which raises the world temperature, is the production of power from fossil fuels like natural gas, coal, & oil. Power production by non-conventional energy sources is proposed and implemented globally to overcome these challenges. Researchers employ a wide range of power electronic equipment, which, amongst DC Converters, are one of the best in regulating voltage levels to improve the efficiency of clean energy sources. This paper proposes transformerless direct current converters implemented in renewable energy applications. A modified CUK converter is suggested with a single power switch, guaranteeing excellent voltage gain and efficiency to overcome the shortcoming of the current converter. The presence of one power switch is used to lessen the switching losses and voltage stress. The novel structure is framed by the cascaded link of step up and CUK converter to obtain a great voltage conversion ratio with a modified structure. Additionally, the benefits of a proposed modified Cuk DC-DC converter sustained the steadiness of input current by boosting up methodology by hybrid technique. Furthermore, the proposed novel converter expanded its functioning in continuous and discontinuous conduction mode functions. MATLAB Simulink executes the performance factors analysis, and an outcome of the projected converter depicts that the modified converter performance has enriched, and its performance is analyzed with existing convert by comparative analysis.
