Triac leakage

Ardent

Hi

Just curious!

I wish to change the phases using triacs - Three triacs are connected
to the three pahses (220V). The other terminals are bound to the
output. By firing selectively a triac the output is connected to the
respective phase.

What will be the problem?

Designing the control circuitry, or coming up with the cash to buy
one that somebody has already done?

This has been routine for decades.

Have Fun!

** If two triacs ever come on at the same time - things will get
interesting...

Better post this question over at " sci.electronics.design ".

It's way outside basic electronics.

Nothing except, you aint changing the phase, you're just deciding when
to turn it on to the output. And on top of that, you need another 3
scr's just to get the other side, since most 3 phase systems have no
common. If you are working with a common and you are only trying to get
DC as the results, I Guess that would work.
