In this paper, a new structure for non-isolated transformerless buck-boost converter is presented. The proposed converter has higher voltage gain comparing to the classic buck-boost, boost converter, CUK and SEPIC converters. The proposed converter has the advantages such as, buck-boost capability. The presented converter has simple topology; hence, the control of the converter is simple. The presented converter has one main switch. Therefore, the switch with low switching and conduction losses can be adopted. The converter offers low voltage stress of the switch. Hence, switch with low on-state resistance can be chosen. The principles of the converter and mathematic analyses are presented. The validity of the correctness of calculations is confirmed by the experimental results.
