Cuk converters are structures that convert a DC voltage to a DC voltage of varying amplitudes. Cuk converters can operate as both step-down and step-up converters. This study addresses the modeling of a non-isolated Cuk converter, its design using MATLAB Simulink software, and its simulations. A discrete-time PI controller was used to control the designed Cuk converter. The output DC voltage graph of the designed Cuk converter was obtained, and a comprehensive time response analysis was also performed. The rise time, settling time, peak time, peak voltage, and overshoot values were analyzed. A comprehensive time response analysis was conducted. The time response data indicate that the designed Cuk converter has a fast rise time, minimal overshoot, and a short settling time. The designed non-isolated Cuk converter can quickly reach the desired 60 V value. The analyses revealed that the designed Cuk converter operated successfully.
