Abstract
This research project focused on the design, simulation, prototyping, and testing of solar-powered impressed current cathodic protection (ICCP) devices integrating supercapacitors for efficient charge storage to combat corrosion of reinforcement steel in concrete structures. Alongside this focus, the study also emphasized the design and testing of a cost-effective Single Transistor Active Constant Current Source Device (STACCSD). This minimal circuit effectively harnessed solar power, managing varying source voltages ranging from 17V to 21V and load conditions ranging from 500Ω to 3kΩ, converting them into stable and consistent currents tailored for (ICCP). The integration of charge storage, notably through supercapacitors, substantially prolonged the duration of the current supply deemed necessary for effective (ICCP), potentially enhancing corrosion prevention measures. Comparative analysis highlighted differences in effectiveness among approaches, revealing that systems incorporating advanced charge storage, despite higher initial costs, exhibited prolonged operational periods compared to lower-cost alternatives. This research highlights the potential of solar-powered devices, including the (STACCSD) and supercapacitors, in corrosion mitigation for concrete structures, emphasizing the need for further exploration to address limitations and discover broader applications within the construction industry.
