opto dimmer
Dear friends
Thank you very much for your helps.
my problem solved.
I solved it by Jose suggestion. my problem was zero cross detection opto.
I tested my board with a MOC3051. that was good.
thank you Jose, Manish and mpp.
and dear mpp I tested it without any load. now before any...
dimmer ac
Dear Manish thank you for your helps
I attached my circuit.
I think zero crossing is good but I don't know exactly that it should cut the wave at a special position or not. I start cutting exactly after rising detection and stop it some millisecond later.
thank you again.
problems connecting a dimmer
I tested a dimmer circuit and i saw the wave of it before and after connecting the lamp. it's wave before connecting is like after connecting and it working good. but my circuit is not like that and my dimmer is not working.
I tested your circuit with a new opto...
dimmer with zero crossing
thank you Manish for your quick response.
I tested your suggestion but still I have that problem.
Picture 2.jpg show output before connecting lamp and 3.jpg show this after connecting lamp.
I don't know what i should do.
please help.
dimmer bt137
hi
I created a dimmer with PIC microcontroller, BT137 triac and MOC3063 opto triac.
I attached an image of my schematic.
I have a problem with this circuit. when I test this board without a lamp, I see a good cut ac signal. but when I attach a lamp to output, I see a uncut ac...
