2024 ASEE Annual Conference & Exposition

Power Electronic Feedback Control of a DC-DC Converter Using an Arduino Uno

Presented at Innovative Pedagogical Techniques in Engineering Education

Rapid prototyping systems to implement feedback controls are expensive. Other alternatives such as analog controllers that include waveform generators complicate tuning by requiring components to be physically swapped. Thus, this research explores the limits of configuring a commercially available digital microcontroller for doing power electronics research. The authors used an Arduino Uno to control the output voltage of a DC-DC converter. The setup of the Arduino Uno and the experiments that were performed are documented. The range of switching frequencies and sampling frequencies that could be used to successfully satisfy the control requirement are presented.

Mr. Junhyung Park United States Air Force Academy [biography]

Mr. Park is a third-year Electrical and Computer Engineering student at the United States Air Force Academy. Mr. Park has devoted his interests to satellites, rovers, rocketry, optics technology, robotics, and the Internet of Things with USAFA Blue Horizon Rocketry Club. Mr. Park has research experience in developing a LoRaWAN transmission system for the weather balloon that shares the flight data with the ground station through the Internet of Things network. He has also developed DC-DC buck converter power feedback control infrastructure with Arduino Uno and tested the capabilities of a hyperspectral camera for identifying small ordnances on a runway as a part of the United States Air Force’s Rapid Airfield Damage Assessment System (RADAS). As a part of USAFA SPARK Innovation Tank, Mr. Park is also a problem solver with experience in pitching ideas at Falcon Tank and Junction Asia Hackathon. Mr. Park hopes for the world that he will change with his ideas one day.
