Abstract

A single-switch step up/down converter with positive and negative outputs is proposed in this paper. In the porposed converter, a single-ended primary inductor converter (SEPIC) and a Cuk converter are merged. The SEPIC converter stage provides a positive step up/down output and the Cuk converter stage provides a negative step up/down output. An input stage consisting of a switch and an inductor is shared. The proposed converter has a continuous input current, step up/down capability, dual outputs, and good cross regulation. The operation principle and steady-state analysis of the proposed converter are provided. A prototype of the proposed converter is developed, and its experimental results are presented for validation.
