BUT, and I don't know how to account for it, there was a very significant non-linearity . Testing over a range of currents from 0.2A RMS to 9A, the slope of the Vout / Iin graph shifted by nearly a
The one turn generated about 0.3V RMS from a 240V input, although after some prolonged testing as a CT, I realised I had got the turns calculation some way out, but thats by-the-way, (it was actuall
Can anyone help with this knotty annoying problem... I wanted to make a 50Hz current transformer (CT) to measure the input current waveform to a SMPSU. I took a small cheap transformer from a wall mo
