Connector Polarity for AC signals

[newbe_always]

I made a connector small board based on this document .In page no 21 you can see "4.5 Load Impedance variation".

You can see that (Figure 36) signal from Bode 100 channel 2 is coming to one end of the load board and the other end is connected to WPT coil.

My schematic is given below.

From Bode 100 signal is coming to BNC and I will select one load at time(either 1R,10R ,22R etc). and the Output of J1 is coming to WPT coil.

I made a mistake in the schematic,the J1's 1st PIN is ground and 2nd PIN is signal.But I connected 1st pin to Signal and 2nd PIN is ground.

The signal coming from Bode100 is an AC signal.My question is will this connection error has any impact or not.

As long as whatever plugs in J1 is wired the right way round (ground to pin 2) it will make no difference - or just fit J1 the other way round.

J1 is connected to a wireless power transfer coil,something like this . As per my knowledge there is no polarity for WPT coils

Then it makes no difference, other than if the lead to it was a screened one, then it makes sense to keep the screens joined together.

Hi,

You cannot detect the phase of a single AC signal if it is a pure sine wave or it is half wave symmetrical. You have to have a reference phase to compare with it, which you do not have. This means the Rx will never know if the phase is one way or another.

If you had a marker generator you could place a mark at the start of zero degrees on the sine and then look for that marker on the Rx side, and could tell you the phase referenced to that mark. I'm not sure if anyone does this anymore though, and it does not matter in this application anyway unless you are just curious.
If the signal got inverted, then you would see the marker at 180 degrees on the Rx side instead of at 0 degrees.

Phase can actually matter a lot when you have more than one phase, but that's not the case here anyway.

There is a possibility of getting the phase wrong on one side though if your circuit includes a shield of some kind. You want to keep the signal line the same on both sides. That can also be important.
