From the project

This project is my attempt at designing a fully programmable bench power supply from the ground up.

This project is my attempt at designing a fully programmable bench power supply from the ground up.

Most hobbyist power supplies are either simple fixed-voltage supplies or rely heavily on pre-built modules. I wanted to understand the entire system myself, from power conversion and feedback control to measurement, user interface, and digital regulation. The result is a custom-designed power supply capable of generating an adjustable output of approximately 0V to 30V at up to 5A from a standard 12V DC adapter.
