Modeling and Control of a High-Voltage-Gain Step-Up Converter for Alternative Energy Systems

https://doi.org/10.58571/CNCA.AMCA.2025.044

Resumen: In this paper, a control strategy for a non-isolated step-up dc-dc converter with a high-voltage gain and reduced voltage stress in semiconductor devices is proposed. This converter can achieve wide voltage ratios with high-power efficiency, which is suitable for applications with alternative sources and batteries. Analysis, modeling and controller design are carried out for implementation purposes. Due to its non-minimum phase dynamics, the proposed controller consists of two feedback loops to ensure system stability and accurate voltage regulation. To verify the performance, a 220 V, 500 W laboratory prototype was built.
