Abstract
Nowadays, switched-inductor and switched-capacitor configurations are widely used for boost DC-DC converters to improve high boost ability. By applying the principle operating of charging and discharging of inductor and capacitor elements in parallel or series connection, it is considered that four diodes, one high voltage rating switch, two inductors are validated to show as a conventional switched-inductor boost converter. In this research, a novel high-boost DC-DC converter based on the switched-inductor technique is introduced. The introduced converter is transformer-less topology and determined by changing the configuration of the conventional switched inductor structure and a semiconductor switch. As a result, the introduced converter can give low voltage rating active switches. Furthermore, the introduced converter is low in cost and achieve higher efficiency with simple topology. The operating analysis of the introduced converter is presented in detail. The simulation results with the output control are presented to verify the analysis.
