A Non-Isolated High Gain Switched-Inductor Switched-Capacitor Step-Up Converter for Renewable Energy Applications
This paper presents a novel of a transformerless step-up DC-DC converter based on a switched-inductor (SL) and switched-capacitor (SC) techniques. The main advantage of the proposed SLSC step-up converter is the ability to achieve very high voltage gain (>20) with reasonable voltage stress across the semiconductor switches. The presented paper shows a detailed analysis of the proposed SLSC step-up converter and a comparison considering other published step-up converter topologies. Theoretically, the proposed SLSC step-up converter can boost the input voltage to 23.5 times when $\mathbf{D}=0.75$, which D means the duty cycle of the MOSFET. Such a large voltage gain can be used in renewable energy applications such as photovoltaic application to boost the output voltage which the output voltage is low. The proposed converter is analyzed in continuous conduction mode (CCM). The proposed converter has been designed for 12V input voltage, 280V output voltage, 200W rated power, 50kHz switching frequency, and 75% duty cycle. The proposed converter has been simulated in MATLAB/SIMULINK.
