| description | This paper proposes a new generalized switched-inductor-capacitor module for a non-isolated dc-dc converter with low voltage dc source applications. Further, the proposed module can be extended to an <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula> number of modules to achieve high voltage gain. The derived structure has low voltage stress on power components. This structure benefits the designer by allowing him/her to choose a low <inline-formula> <tex-math notation="LaTeX">$r_{DS}$ </tex-math></inline-formula> (ON) switch due to the low voltage stress across the semiconductor devices, resulting in high efficiency and low cost. In most dc/dc converters, the voltage stress on the output diode will equal the output (high) voltage (<inline-formula> <tex-math notation="LaTeX">$V_{o}$ </tex-math></inline-formula>). But in the case of the proposed topology, the diode voltage will be the difference between <inline-formula> <tex-math notation="LaTeX">$V_{o}$ </tex-math></inline-formula> and the input voltage (<inline-formula> <tex-math notation="LaTeX">$V_{g}$ </tex-math></inline-formula>), which eases the reverse recovery problem. The key metrics of the derived topology, such as component count, voltage stresses, and gain factor, are analyzed to compare with similar existing topologies. The scaled down prototype setup is developed for 200 W with an efficiency of 93%. Finally, various experimental results are discussed for the different duty cycles. |
