Hello,
The goal is to control thru a triac a low power 24VAC load, by a 0-10VDC setpoint
Generating a synchronizied ramp and zero crossing detection, comparating and firing the triac is well known.
BUT : is somebody knowing an IC to do that (the goal is space saving) ?
Thank you for your ideas
Hello Colporteur,
You are right : it's the first time I'm trying to get an answer using a forum !
And you are right again : a little drawing will help ....
So ... the basic question was : does somebody knows if there is a supplier who has integrated the red surounded part of this simplified schematic (or similar function, or a part of it, ...) in a DIL6 ?
The T2 - T1 stage is the synchronized ramp building, the comparator is ... comparing, with the DC set-point, and the UJT stage firing the thyristor.
It is simple intelectual curiosity
Actually I'm firing the thyristor trough a pulse transformer, because I don't like the link between neutral and DC power zero, and some other implementation reasons.
Thank you again for your patience, and sorry for my poor english, I don't trust translating softwares ...
Best wishes
Piper
