الملخص | In this paper, a new Transformer-less Boost Converter (TBC) is proposed to achieve high step-up voltage with a reduced voltage across switches. The proposed topology has the advantage of providing a high voltage gain, the low voltage stress on the active switches, simplified control, and high efficiency. The structure is derived by modifying the classical Switched Inductor Boost Converter (SIBC) by replacing two of the diodes with a capacitor and a control switch, which results in a total output voltage equally shared by the two switches. Thus, the proposed converter needs a lesser number of diodes than the conventional SIBC, where the two active switches equally share the total output voltage and thereby reducing the voltage stress across the switches to half. Hence, low voltage rating switches can be used to design the proposed TBC structure. Also, a higher voltage gain is achieved using TBC without increasing the number of components of the existing SIBC. Furthermore, the proposed converter provides the common ground connection of source and load. The detailed analysis, effect of non-idealities, design, and comparison are presented. The experimental results of the proposed TBC are presented to validate its functionality and theoretical analysis. |
