Abstract/Summary
This project presents the design and implementation of a DC/DC power converter intended for photovoltaic (PV) modules with varying electrical output characteristics. Solar panels experience significant changes in output voltage and power due to variations in sunlight, temperature, and load conditions. To ensure reliable operation across a range of conditions, the proposed converter is capable of both step-up and step-down operation to accommodate solar modules with power ratings from 50 W to 450 W and open-circuit voltages between 10 V and 80 V. The system operates at load currents up to 10 A and provide a user-adjustable output voltage within the range of 5 V to 50 V, allowing for compatibility with a wide range of electronic loads. Key considerations in the process of designing the converter include topology, control strategy, component sizing, and protection features such as overcurrent and overvoltage protection. The resulting converter demonstrates a flexible and practical power-conditioning solution for photovoltaic energy systems.
