In this study investigation is done on an H-bridge switched inductor base cascade multilevel DC-DC boost converter. The proposed multilevel DC-DC boost converter topology improves the conversion efficiency of traditional topology. The proposed boost converter topology is differing from the traditional topology by the addition of switched inductor circuit. The switched inductor improved the conversion ratio gain of the boost converter circuit. The switched inductor provides a very large output voltage with different output DC levels which makes it suitable for multilevel application. Then, the mode I and mode II of operation of switched inductor are analyzed. The use of proposed switched inductor base multilevel DC-DC boost converter improved the power quality and reduced the switching frequency. The proposed DC-DC boost converter topology simulated in MATLAB/Simulink working platform and the conversion performance is evaluated. Then, the conversion performance of proposed H-bridge switched inductor based topology is compared with single level and multilevel cascade boost converter topologies.
Key words: Cascade multilevel, DC-DC boost converter, operation mode, switched inductor, , ,
