- The person in this video makes a transformer that does not have separate primary and secondary windings. How is this supposed to work?
I have always longed to make a system where I can get AC over a wide range of voltages. This system would help me test how my other experiments behave when they are powered from the mains. In order to get different voltages, I need to design my own transformer where the secondary has been tapped at different places so as to give different voltages.
On YouTube, I found this video. The person winds transformers at his home. The video is not in English, so you can jump to the section where he shows his circuit:
The input is on the left (where his finger is), and the output is on the right. As you can see, he starts the primary winding, but instead of ending it, he bends it into an output terminal, and thereafter continues winding the secondary coil.
My question: I have seen transformers that have two wires for input (live and neutral). Here there is only one input wire. So, will the neutral be common from the input to the output? One end of my load will connect to the A, B, C, D or E terminals on the right, and the other end will be directly attached to the second input wire (that has not been attached to the transformer) - is this correct?
