At this stage of my learning I'm still a bit vague about wiring of transformers and what is possible. I have successfully removed windings to lower output voltage and have also successfully wired twin secondaries in series and parallel. I still have lying around a toroidal with twin 18VAC secondaries and wondered whether this can be used, like a centre tapped secondary to produce positive and negative rails (i.e 18V -0V -18V) ?
I've done lots of internet research and most articles suggest that positive and negative rails can only be created using centre-tapped transformers. I have however found two brief articles that suggest I can do it with twin secondaries. The transformer I have is this one of these (the MCTA160/18 variant). I am attaching an image showing, on the left the normal secondary arrangement and, on the right the configuration which, it is suggested, will produce an 18V -0V -18V output. I would be grateful if you knowledgeable folk could tell me whether this is possible and, if so, are there are any traps I need to be aware of.
If it is possible I would also need to try and get my head around how the rectification would be done.
Regards
