has anyone tried to use 2 r/r's in parallel?
as the output from the stator has to be used regardless whether it's a useful load or just the r/r taking up slack, by sharing the continual load from the stator they would not only last longer but you would have a redundant system for when one does fail.
curious of thoughts on this as i think i'm going to try it.

You can do that however you would have to do something to balance the load from the output side and provide a means to switch over to the good one in the event of a single failure. Other wise you would split up the bikes loads with half on one regulator and half on the other.

At a minimum, you would need to isolate the output of each r/r with a diode to prevent reverse biasing the output transistors in the regulators. That means you would be dropping the output by 6/10 to 7/10 of a volt to the rest of the system.

In other words it will not work, just carry a spare if you are concerned of it going south.

can i get a little clarification. reverse bias?
i intended to completely parallel, load and supply. same ac source shouldn't buck each other and dc is easily paralleled. the only prob i'm unsure of is if the regulators would fight each other, but if the idea is to keep 14-15vac ....it would seem ok, but alas, me no electronic engineer keemosabi.

Running both on the same ac feed would not be a problem but feeding out both into the same circuit can be a problem. If the regulators are not fairly clean then there may still be enough of an ac wave to require them to be synchronized so they are in phase or they might heat up. Better option would be to just get a more heavy duty single regulator of similar configuration if longevity is a concern. Having two running at the same time could also overload the stator and lead to its early failure. Remember there is not much researve capacity on some bikes. |
