Step-Up Three-Output Single-Switch DC-DC Converter for Solar Cell Applications

In this article, a multi-output DC-DC converter is introduced with the integration of super lift Luo converter, sepic, and boost topology. The proposed single-input multi-output converter simultaneously generates step-up voltages in its three outputs. The proposed non-isolated step-up converter with a simple structure, using a switch and low voltage stress on the switch is introduced for the application of renewable energy. Circuit theory analyzes are presented in the continuous conduction mode and evaluated by the simulation results. The control of the proposed 110-watt converter, along with providing output control for input changes, has been investigated. The efficiency of the converter is about 91% in full load; to confirm the superiority of the converter, the efficiency of the proposed converter has been compared with the similar multi-output converters.
