Sorry, I donot understand. Is it not allowed by any standards? Cause, my customer asked he has a 3.6kW IR heater.I don´t think it´s allowed to use a 3.6kVA dimmer
Yea, I measured rms value using multimeter. and it does show 230V line to line.you say "230V, 16A", but are you sure you have 230V between red and blue?
I realize the mistake. Definitely I want to do phase angle control to control power delivery just like a normal dimmer works on singlephase AC.you say "dimmer" so I guess "phase angle control" ... but your optocoupler-driver shows a "zero crossing circuit".
You should do the same on both edges. For negative half wave and positive half wave equally.When I get a high edge on this circuit, I start timer and I trigger MOC3021 opto
Some options:I think if someone can help me get a SINGLE waveform that shows voltage variation of R only w.r.t B most of my confusion gets solved.
Yes. agreed. Im doing the same.ou should do the same on both edges. For negative half wave and positive half wave equally.
Ok, so I used matlab to plot this R-B (orange). This is supposedly variation of R if B is held at 0. It seems alright.For simulation: just draw your voltage signal as "R-B" --> subtract one from the other.
From plot I understand, driving technique can be same, doesnot matter if R&B is connected or Live&Ntrl connected. It's the Amplitude of sine wave change that needs to be considered while designing a circuitry. Please confirm this conclusion is correct.Keep in mind: The function does not depend on EARTH at all. It will work on the ISS or on Mars or on every other isolated system.
>> x = sin(2*pi*(50/1000)*[0:79]);
>> y = sin(2*pi*(50/1000)*[0:79]+(2*pi/3));
>> plot(x-y);
>> plot(x);
>> hold on
>> plot(y);
>> plot(x-y);
Neither "heater" nor "IR" nor "3.6kW" is the problem.Sorry, I donot understand. Is it not allowed by any standards? Cause, my customer asked he has a 3.6kW IR heater.
Oh! I want to keep mains clean, as I want to build a good product. So please answer What do you suggest that I use for this type of 3.6kW load (basically patio heaters) ? Triac or Mosfet or any other?At least in Europe one needs to keep on regulations to keep the mains voltage "clean".
