A High Voltage Gain Boost Converter with the Reduced Number of Switches Using the developed Switched Inductor and Capacitor Structure

Abstract

This paper proposes a new boost converter topology to address the compatibility problem with a high voltage gain compared to the conventional boost circuit, which is highly proper for renewable energy resources and DC applications. In contrast to similar boost converter configurations, the proposed topology has fewer semiconductor components. Furthermore, the output stage is removed, as the switched inductor is developed by replacing two diodes with two capacitors. Moreover, the symmetrical circuit makes design and analyses less complicated. The operation modes and the steady-state analysis are accomplished in the current conduction mode. The converter simulation is carried out with MATLAB Simulink and Script so as to obtain the typical waveforms of the DC-DC converter.
