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.
