Abstract
Based on the working principle of strong-flow cathodic protection system, the main circuit topology of AC-DC-DC was built using the fully-controlled switching device MOSFET. The hardware and software design of the digital signal processor DSP was used to develop the control circuit, and a strong-flow cathodic protection system was constructed. At the same time, in MATLAB development environment, SIMULINK module was used for simulation modeling to verify the protection performance of the system. The results show that the system could meet the needs of cathodic protection under strong-flow conditions.
