Abstract
This paper presents the design and simulation of a high step-up DC-DC converter employing a passive quadratic gain circuit integrated with a single active-switch boost topology for sustainable power source applications. The proposed quadratic network consists of a diode-inductor-capacitor configuration, connected at the input side of a conventional boost converter. The inductor in the passive gain circuit is periodically energized by the main active switch trough a diode, enabling higher voltage transfer and store at the intermediate capacitor. The stored voltage is subsequently step-up by the conventional boost stage, resulting in an overall quadratic voltage gain. The operating principle and steady state voltage gain characteristics of the proposed system are analyzed. Simulations are conducted to validate and evaluate the converter performances. The results demonstrate that the proposed topology achieves a significantly higher voltage gain compared to the conventional boost converter under identical duty cycles. The proposed passive quadratic converter provides advantages in terms of reduced complexity, lower cost, and improved suitability for renewable energy power systems.

This paper introduces a non-isolated high step-up DC–DC converter suitable for distributed generation system applications. The proposed topology uses the zero-voltage-transition (ZVT) technique to achieve soft-switching conditions over a wide range of output power levels, resulting in improved efficiency and reliabilit...
Conventional quadratic boost DC–DC converters can achieve high voltage gain; however, the main switch is subjected to voltage stress approaching the output voltage. Some improved topologies also suffer from limitations such as the absence of a common ground, discontinuous input current, or increased control complexity...
