I'm just starting to build a coffee warmer, and it would be useful to get some assistance from others more experienced.
Basically, I want to control the temperature produced by the peltier plate using PWM instead of a regulated power supply. The idea is to send more pulses to the plate when I want to increase the temperature and decrease the amount of pulses that I send to the peltier plate when I want to reduce the temperature.
This is accomplished by using the serial port of the computer, that controls a N-Mosfet transistor, allowing more or less power to pass through the peltier module producing more or less heat.
These are the characteristics of the peltier module I have:
Umax (V): 15.2V
I max (A): 6A
Tmax (degree Celsius): 67
This technique of controling the temperature (Pulse Width Modulation) can be used to regulate the temperature produced by the peltier plate or is it only possyble using a controled power source?
