In this study, a novel buck–boost DC/DC converter is presented. The circuit structure of the proposed converter consists of a single power switch, two diodes and some energy storage elements. Employing only a single power switch reduces the implementation cost and switching power losses. The proposed converter has higher voltage gain in step‐up mode in comparison with conventional buck–boost and Cuk converter. In addition, this converter expands the continuous conduction mode (CCM) operational region. The presented converter has three operation modes in CCM. The second mode reduces the voltage stresses across the capacitors. Therefore the current stresses on diodes are also reduced. To verify the operation of the proposed converter, the experimental results are provided using a hardware prototype.
