13 8 Volt Regulated Power Supply Schematic Diagram. 12v 10a regulated power supply. Part list for 20 amp bdx33 based power supply.
20a transformer is very very expensive large in size and very heavy in weight. 20a transformer is very very expensive large in size and very heavy in weight. Using pass transistors beef up voltage regulator current output.
A good idea here is to start to use colour coded wire to identify the voltage rails perhaps orange for the un regulated supply red for the 13 8 volt regulated output and black for negative rail.
Adjustable voltage regulator using a 7805 or other fixed linear voltage regulator instead on lm317. 12 volt gel cell charger circuit diagram. Using pass transistors beef up voltage regulator current output. This 13 8 volt 20 a regulated transformerless power supply.
