Greetings to all.
Lets discuss about my problem -
I am making a power supply to power Audio instrument having 12V 1.25A rating across the output.
Here is my circuit -
Now when I connect the AC it is working as expected but the problem is I am feeling AC shock of low voltage across the output. When I conenct a neon tester it is glowing on both the outputs.
What I have done, I have connected a Filter (3.3uH Choke) directly with the secondary RTN and the Earthing like this way -
Sorry for my poor image.
The Neon doesnot glow, and I do not feel any electrical shock like sensation in the above case.
I want to use this smps in locations where the Earthing will be a problem. So, is there any way to eliminate this issue without earthing. (I want to have earthing option as well).
Thanks a lot to all.
