Hey guys
I know that i need to maintain a glass envelope temperature for a successful halogen cycle however i haven't come to any definitives on the use of PWM for halogens and how this can be implemented for the application of a heating element.
I am looking to use closed loop control to maintain a thermal set point.
For nichrome wire or a ceramic heater this is as simple as just using PWM to give a variable average voltage for varying power dissipation, however the halogen has constraints imposed on it by its physical composition and i am not too sure on how i can implement PWM control of the halogen for eventual PID control of a set point without reducing the lifespan significantly by fouling the halogen cycle efficacy.
