Design and Implementation of a High Step-Up Boost-Sepic Hybrid Converter with Soft Switching
Journal Title: روش های هوشمند در صنعت برق - Year 2015, Vol 6, Issue 24
Abstract
In this paper a compound boost- sepic converter with soft switching for high voltage application is proposed. One of the advantages of this converter is that, the main switch is turned on under the ZCS condition without need to any auxiliary switch so we have lower switching loss. In order to increase the voltage gain in this topology, a boost converter used in series with the output stage of sepic converter, therefore the output voltage of boost converter added to the output voltage of sepic converter and the voltage gain has been increased. Also a coupled inductor has been used in the boost converter topology which leads to a further increase in the voltage gain of the converter. In order to evaluate the operation of the proposed converter, simulation results and analysis of converter operational modes are presented. In addition, experimental results are presented for a typical boost-sepic converter. These results verify the proper operation of proposed converter.
