Reversible rectifier.

[MikeP]

 Hallo.
 Please share information and examples about reversible rectifier. That is, we are talking about the possibility of changing the polarity of the output voltage.
 Thanks.

for what purpose ?

[KD0CAC John]

1st same as last - what are your trying to do ?

I ask , because I do not think there is such a thing - rectifiers are made with diodes = diodes pass current in one direction " only " ?

Half way - 2 diodes
full way - 4 diodes

leave the rectifier alone and just swap the output wires around

[HackedFridgeMagnet]

something like that, except change the battery for the rectifier.
the switch contacts wont like the motors though.

HackedFridgeMagnet's example is goof if you want to use a manual switch.  The electronically controlled equivalent of this is called a "H-bridge".

Are you after sinusoidal output voltages (hard), or just reversing the direction of a DC voltage (easy)?

That brings back memories of very early 60's.  Popular electronics had a project with a transformer, germanium power transistor  and low ohm pot. Essentially they used the transistor as a dual diode and the pot would eventually short out one diode or another.
