Hi, this thread should not be about how to make the oscillations stop, but rather how to make them going.
I am building a simple temperature regulator, and I am trying to reduce the temperature variance by making the comparator work in a "pwm regime". The idea is that as the comparator reaches the treshold, its output should start to oscillate to produce a lower power on the heater, and as the temperature rises further the oscillations should stop and the output should be in off state permanently. It would be perfect if the duty cycle will be changing through the transition, but it is not necesary.
Any idas how to introduce the right amount of feedback to make it work like this? My idea of the frequency is less than 10kHz.
