I'm participating in project of create small thermal calibration chamber. I would like to get to know this topic. At this point I know that peltier module will be driven by voltage not PWM. That's because of provide general stability of the system.
How I can create such circuit? I don't think about temperature sensor just microcontroller that drives this peltier module. Let's say that my stm32 doesn't have DAC. Do any digital volrage regulator exist? Would it be nice to use adc and then drive voltage regulator or opamp? Do voltage regulator would be sufficient for peltier module?
