Design and Implementation of Modified SEPIC, ZETA, Cuk, Quasi Z-Source Converter for BLDC Drive System – A Comparative Analysis

For the system to work properly, it needs a suitable DC-DC converter. High output voltage and power, low harmonic distortion, low ripple content at both current and voltage, and high efficiency gain with fewer component requirements are just a few of the parameters for a good converter. A lot of the converters are made to meet some of the aforementioned requirements. With increased potential for BLDC drive-based Electric Vehicle (EV) applications, the converter chosen in this article is one that will be suitable for those applications. Before recommending a converter for a certain usage, its performance must be evaluated. Various converter topologies are considered. The validation process goes into great detail for the design topology, components used, equations created, loss calculations, and output performances. The majority of converters perform better than expected when choosing the right component values. Applications that work well are provided together with the findings of the converters and the related values.
