Abstract

In this paper, a new transformerless buck–boost converter is introduced. The proposed converter voltage gain is higher that of the conventional buck–boost converter. In the presented converter, only one power switch is used. The switch voltage stress is low, therefore, the low on-state resistance of the power switch can be selected to decrease losses of the switch. The presented converter topology is simple, hence the control of the converter will be simple. The mathematical analyses and principle of the proposed converter are explained. The validity of the proposed converter is confirmed by the experimental results.
