Hello There,
Hope this post find you well.
May be or may not you would love it, because this issue has reached huge number of problems.
Someone could say "school project for infants".
I was trying to build a SOLID STATE RELAY with zero crossing switching.
Similar to this product, **broken link removed**
In my case I was using MOC3021http://www.farnell.com/datasheets/97984.pdf and BTA100-800A.
dv/dt of BTA100 is 500V/us.
My application is 380V 40A load switching.
Lets say for inductive and capacitive load.
Main issue is "someone said me not to use any microcontroller to drive the TRIAC gate".
So, random switch type SSR has been chosen,
It might be non-zero crossing type SSR. 5V dc as been used that does not make sense for gate switching or its keeping the gate ON always.
How about using a TIMER as follows?
Can we control zero crossing with this idea?
