Maximizing efficiency and power quality: A deep dive into hybrid buck-boost, cuk, and SEPIC converter topologies

Abstract

In power electronics, DC-DC converters play a crucial role in industrial power supplies and

battery charging. To increase efficiency, simplify design, and enhance power factor, a single- switch hybrid converter integrating SEPIC and Cuk is introduced in this work, along with

comparisons of hybrid Buck-Boost, Cuk, and SEPIC topologies. The suggested converters increase efficiency while reducing size, cost, and total harmonic distortion (THD) by eliminating the need for transformers. These hybrids perform better in simulations than traditional designs, making them perfect for low-THD, high-efficiency applications in contemporary power systems. In addition, the safety road to make the load operation with high performance to minimize the overshoot at the starting operation of the converter, by using that technology can reduce that risk.
