Topic: AC/DC? (3 msgs / 46 lines)
1) From: AlChemist John
I am looking at adding a couple of DC components to the drum roaster I am 
building.  I have no idea how to do this really.  I noticed when I rewired 
a WBII that it had four components wired into the DC motor so I assume 
there is a straight forward way to solder in the proper components.  If 
anyone can help with what these are and how to design properly, please 
e-mail me privately as this is only vaguely related to coffee.
Thanks.

The 4 componets are diodes which is used to rectify ac to dc. I am also guesing
that they are not seeing 120, but a voltage dropped version of that.
For more information look on the web. Your car's alternator uses diodes to
produce dc.

Search terms: full-wave rectifier, half-wave rectifier, bridge rectifier.
Reasonably simple design guidelines.
