#74224 - RE: Ramping instead of zero-crossing
Responding to: ???'s previous message

Bartosz said:

That is, if PWM goes all the way as PWM. Run it through a simple low-pass filter (a capacitor plus a resistor to ground) and it turns into a neatly smooth analog signal like right from a DAC.

Agreed. But this would work only for devices which can be operatd linearly like BJT and not for triacs. So this smoothing of PWM fails on triacs.

we need more "linear" solution - like an optocoupler with somewhat linear characteristic.

Again, this is not going to work on triacs.
