I am looking for a comprehensive reference on Thermoelectric coolers, a.k.a Peltier devices. I need information such as how one should control them, how to control with maximum efficiency.
I have seen a few applications where PWM is used to control them and wondered, in particular, why they would not just use a DC voltage since with a PWM over 1Khz, the Peltier device will only "see" the DC average of that pulse train anyway.
What about controlling these in an Automotive environment? Any special considerations to think about? Are Automotive environments particularly noisy? Are noise or interference frequencies you would expect to see "floating around" which differ for various manufacturers, countries, regions?
