| Oct 12, 2016 at 9:24 | comment | added | Rohat Kılıç | You've to place an electrolytic capacitor across the output terminals of bridge rectifier (e.g. 470uF). Please, first, read some tutorials about basic AC-DC conversion. Here is a good reference: homemade-circuits.com/2012/03/… | |
| Oct 12, 2016 at 9:14 | comment | added | user126396 | I have removed the ground near the supply, connected the common to the return terminal and grounded it and have removed the Multimeter replacing it with a current probe. puu.sh/rGhMi/6e0b94ef68.png I have no measurement of the output DC voltage now and the peak-peak is too high. Any suggestions please? Thank you :) | |

| Oct 12, 2016 at 9:03 | comment | added | Rohat Kılıç | Your connections are totally wrong. 1) Don't connect the system ground to your 240V supply. 2) Regulator IC's COMMON terminal should be grounded as you did, but this terminal should also go to the bridge rectifier's left-most common-anonde terminal --since it provides a return path. And finally, 3) Don't even try to place an ammeter (XMM2) across the output terminals. | |
