Dear all,
I'm trying to build a controller system for a heating system, based on a microcontroller.
I would like to actually implement a PID control instead of an ON-OFF one by using a temperature sensor and controlling the RMS current of the heating element using the PWM output of the controller and a .... And here is my problem!
I need to be able to PWM the current of a 2kW heating element, but I fear (maybe wrongly) that the current is a bit high to use a TRIAC on an inductive load.
I have also thought of using an IGBT or thyristors in anti-parallel. But in reality, I have a tough time deciding which is the safest, easiest way to go.
What would you recommend?
