Re: Please explain doubling

209.215.72.221

If a current passes through only ONE line, either the hot OR neutral, then it will induce an equal but opposite voltage in the other coil winding of a common mode choke. With an equal but opposite voltage, the original voltage is doubled.

Of course, there are losses, and depending on the coupling, etc. , the voltage will not actually double, but it will still be bigger than the original voltage.
