Hi,
Thinking of a circuit to control the AC power to a heating element. I wanted something fairly linear, and analog. I don't have anything against using a programmable controller, I just wanted to think of an analogue solution, seeing as I don't need to learn how to write a program.
The attached image shows the flow diagram and circuit sub-section schematics. It works in my simulator.
Just wondering if there is a better way to go about this? Switching on/off whole/half waves in a duty cycle?
Cheers,
Archie
*edit - that's a 555 IC in the pwm section
