This project was completed by the request of Professor Cooney. The goal of this senior design project was to create an automated power supply test unit. This automated power supply test unit is needed to reduce the time to test students’ power supply projects. This report will cover the design process and testing process in depth. A replica of the project could easily be made using this documentation. The zero-crossing detector, triac control circuit, DC measurement circuit, and ripple voltage measurement circuit are all thoroughly documented. The full code for the Arduino Due and Nano is also included. Test results are shown for each step of the testing process. Overall, the project was a success. Small improvements could be made, and will be covered in the recommendation portion.
