Abstract/Summary
In this project, a hardware implementation of a current-source DC-DC converter for powering sensors used in an underwater communications system is presented. The proposed converter is designed to step down an input current of 0.9 A to 0.625 A, while maintaining an output voltage of 24 V and output power of 15 W. An overview of the system design is explained as well as the component selection process. The design of the converter was simulated and evaluated using LTspice before being physically constructed on a printed circuit board. Performance evaluation of the proposed converter was carried out in multiple lab tests while varying the input current, duty cycle, and load size. Results of the lab tests demonstrate the proof of concept of the design and the expected trends that are consistent with the previously derived transfer function of the converter.
