Here's another Isolated Transformer, connected as an Autotransformer - in this case, the connections are Series Subtractive - making it a voltage "Bucking" transformer.
The schematic "Boost Transformer" is very similar, except the connections are made in Series Additive format.
BTW: The "Buck" transformer is a mirrored image of the "Boost", the inputs and outputs are reversed.

FYI: The "PHI" symbol on each schematic represents positions of phase polarity [direction of magnetic flow in core as to direction of currents in windings]. That's the key issue of how and why these Autotransformers [connected as Autotransformers] can do the Buck / Boost thingee [technically speaking ]

Any comments???

Scott,

You forgot the // in the link. I took care of it.

I would like to see the ΓΈ symbol added to the appropriate poles on the single phase transformer diagram you previously posted.

Could you help me out with this?

Dspark,

I'll add them, then resubmit to the existing topic[s] under the same names/message bodies.
