1992Chevy K1500 Posted November 12, 2009 Report Share Posted November 12, 2009 (edited) Like the title says, can I use what's known as a "current steering" diode (Source: wikipedia "Current Steering") inline before the battery that powers a power inverter? I know most power inverters can induce noise in a system (though I'm unsure how they do it), and that's why I was wondering. Could I use something like one of these: http://www.allelectronics.com/make-a-store...-25A-45V/1.html Or one of these: http://www.allelectronics.com/make-a-store...TIFIER/-/1.html Also, could I use more than one diode? I'm going to be stuck using an inverter for my setup (I already have 3 or 4 laying around, so it'd be cheaper).

Neel Posted November 12, 2009 Report Share Posted November 12, 2009 (edited) A diode bridge is whats used to convert AC to DC, you need to convert DC to AC. What are you trying to power on 12v? Audio and computer stuff runs on DC , so all you have to do is bypass the original AC to DC power supply and replace it with a DC to DC power supply.

I plan on switching computers a time or 2. So I'd need a DC to DC converter that had a switch (without costing me a lot). Do you know of any that take 12V in and put out 18.5 volts? It needs to have at least a 3.5 amp output. Thanks.

Neel Posted November 14, 2009 Report Share Posted November 14, 2009 This one can do 4.7 amps at 19v http://www.opussolutions.com/index.php?p=product&id=55 Quote Too Much Stuff to list . Link to comment Share on other sites More sharing options...
Shyne151 Posted November 14, 2009 Report Share Posted November 14, 2009 I would hook it up first before I went into trying to wire diodes inline with it. I've put in alot of power inverters with all sorts of equipment and have got engine noise maybe once from one.
