A Single-Switch Step-Up Dual-Output DC-DC Converter for Renewable Energy Applications

In this article, a two-output step-up converter which is suitable for renewable energy applications is proposed. The proposed topology is composed of super lift Luo converter with a switch-capacitor structure to provide a dual-output converter. The proposed non-isolated step-up converter has a simple structure using just one switch and a single inductor for creating a step up two output converter. Circuit theory analyzes are presented in the continuous conduction mode and evaluated by simulation results in OrCAD software. The control system of the proposed 200-watt converter is utilizing one PI in feedback control system. The efficiency of the converter in full load is 94%. The superiority of the proposed converter compared to similar two-output converters is also confirmed.
