A novel buck–boost converter is presented in this study. This converter is based on Cuk converter. Therefore it inherits all the advantages of Cuk converter such as low output voltage ripple and minimal radio frequency interference. In addition, some implementation problems of KY converters are solved. The proposed converter has higher voltage gain in step‐up mode in comparison with Cuk converter. Moreover, this converter expands the continuous conduction mode (CCM) operational region. In the suggested topology, the gate of the switch is referenced to ground, so this converter does not need a floating gate drive. Simulation results of the suggested converter are presented in different operational conditions. To verify the operation of the proposed converter, experimental results are provided using a hardware prototype that operates in both CCM and discontinuous conduction mode.
