From the project
Open Source Lab Power Supply
This project is to create an open source modular lab power supply. The power supply is designed to:
Provide between 0-15V @ 5A and 15-30V @ 3A Provide current limiting Voltage to be settable to within 1mV and current limit to 1mA resolution. Voltage/current readback to 1mV and 1mA with low temperature drift. Limit heat loss through the use of a pre-regulator. The pre-regulator uses an SCR and MOSFET arrangement to reduce noise (switches at a low frequency) Digitally controllable via a Raspberry PI and touch-screen interface. Multiple channels (designed for 3). Each channel is isolated and…
