Hello, Can anyone give me a lead on how to implement a controller in FPGA (VHDL) to control the heating of a tube based on PWM values? I already have the PWM Min, Max values. Thank you in advance!

Just go one step back, act like you never heard ANYTHING about your particular problem, then read your post and think, what information is missing. Then some very basic questions will arise: What kind of "tube"? What kind of "heating"? Do you have any kind of hardware? What does "control" mean to you? How did you get those PWM min and max values? Whats the PWM frequency? Wht is the PWM used for?

The task is to control the heating of the tube which in turn produces tube current. > Do you have any kind of hardware? Altera Cyclone IV running on NIOS2 > What does "control" mean to you? Based on PWM values, the controlling unit has to produce the tube current by controlling the heating voltage. > How did you get those PWM min and max values? Via a PWM Generator module which exists. > Whats the PWM frequency? 150MHz > Wht is the PWM used for? To control the inverter output. I hope I have provided the required details.I have very little knowledge in this field. Any suggestions will be appreciated. Thank you!
