rectifier/regulator wiring

Post by Chewy »



i am always doing some little project or another. my latest project has nothing to do with a goldwing, except the spare reg/rec from my 81. can anyone tell me if i can hook it up to a 110ac outlet from my house and get dc current from it? if i can do this, what would be the best way to go about doing so?

No way for the regulator. It is a shunt type that tries to ground any excess voltage.
The rectifier might work, but it is made to take a 3 phase input.
It would just be a lot easier to buy the correct parts and they are cheap.
A 10 amp 600 volt full bridge rectifier is only a buck or two.

i know, but i like to use things for something they werent made for. im currently using a pc power supply to power a car amp and subwoofer for my computer audio output.

I would really caution against doing this. It is definitely not rated to take 110 VAC, and more importantly there is no isolation (i.e. no transformer) between the input and output, so your "12 volt DC" output is actually for a portion of the waveform connected directly to the 110 VAC current. Potentially lethal if you happen to touch it, and depending on which legs you happen to choose to use, the ground of the 12 volt output could be that "hot" leg of the AC phase. The case of the radio is grounded, and if you touch that...and something grounded, that could be the end of you.

Not that it would likely operate long enough for that to happen, it would most likely go up in smoke and/or flames before that happened - and take out the radio you were trying to power at the same time.

Even if you somehow did get it to function, keep in mind that rectified AC is still a sinusoidal waveform, and all you'd likely hear from your radio is a very loud 60 Hz BUZZZZZ

So...basically, don't try this.

this is why i ask questions to the people who know more about this stuff than i do.
