The purpose of this project is to design and build a DC Power Supply, using digital means, which outputs a constant voltage to current ratio. To accomplish this task, a Buck-Boost converter is used in conjunction with a microcontroller, allowing for digital control over the power supply unit. A Buck-Boost converter is used to adjust the output due to its variability, allowing for an output voltage that is either lower than, the same as, or higher than the input voltage. This is achieved through the use of a current sensing device and digital rheostat, which allows the microcontroller to know what the current is on the output and make changes as necessary.
