PC Controlled Power supply 02 ECE342-SP22
This programmable power supply takes 120VAC wall power and converts it to usable DC power ranging from 2-14v with a max current of 1.5A. Our power supply is composed of a AC->DC rectifier, an Arduino R3 as our microcontroller, an LM75A heat sensor for our safety requirement, and an op amp for each channel. We used a LM358N combined with a custom designed PCB for mounting and installation. Our project taught us a lot about the design process and how to handle unexpected challenges. The experience of our BJT failing has shown us that multiple option are needed incase our preferred method does not work out. This experience also taught us the importance of teamwork, even though we had many setbacks we were able to end our term with a fully functional power supply that we built from scratch!
