This power supply can be used to power circuits that do not require regulated voltages that can be around 6 V, 9 V or 12 V with currents up to 1 A. The transformer has primary according to the local grid and the capacitor of 1000 uF may have larger values for a lower ripple level. Among the devices that can be fed without problems by this source we can mention LEDs, Motors and Solenoids. The circuit is from the book Mechatronics Sourcebook by Newton C. Braga, published in the United States.
