Description
This power supply module was built as a requirement for one of my electronics courses. The goal of the project was to design an analog circuit which converts ~15VAC to ±10VDC and can act as a reliable power source for other small-load devices (full load of 430Ω).
The circuit contains a center tapped 15VAC transformer, a full-bridge rectifier, a low pass filter and a Zener regulator. My final prototype met all performance targets, including low ripple voltage, tight regulation and minimal power loss.
This project was a great opportunity to practice hardware design and I've since used it to drive op-amps, MOSFET gates, microcontrollers and other small-load mixed signal circuits.
