Triacs in //
Hi
I guess you are talking of using 2 or more triacs in parallel, with the same gating control and the same load. From the design viewpoint I think the following points should be taked care of
- Triacs and other devices are not ideal, which means that although ideally they will behave synchronized, in practice it may not occur because of the physical differents from one device to the other. Unless they are built in the same semiconducor buffer the assumption is that they have different characteristics, even though they are infinitesimal.
- These differences will be present at the triggering times, and at some point fewer than expected triacs may be working, These abrupt changes in current may distort the sine wave which the triacs are feeding to the load. In fact, it will be very interesting if you can see this phenomena with an oscilloscope once the circuit is settled.
- In order to make the cirduit to work you may need to compensate the triggering differences by using coils and capacitors. it seems a bit complex, It would be good to know what your load is. I mean if it is a motor, I rather use relays to get the work done, if you are controlling light cicuits, there should be no problem at all
good luck
