Abstract

This paper presents a positive output cascaded boost converter design based on wide bandgap power devices for photovoltaic (PV) applications. The objective is to enhance the converter’s performance and efficiency. The converter with SiC MOSFET devices is discussed and compared to a conventional cascaded boost converter based on Silicon (Si) devices. A 205 W cascaded boost converter with an input voltage of 26.6 V and an output voltage of 400 V is simulated to examine the switching behavior and energy loss of each power device. Converter performance with these two power devices is analyzed in terms of total power loss and efficiency at high switching frequencies and loading conditions. SiC power devices in the cascaded converter set-up perform better with minimized switching loss under a wide range of switching frequency conditions. The results show that the cascaded converter with SiC devices significantly reduces total power loss and improves the overall efficiency.
