Hi guys,
May I know what is "control the direct current using SMPS to drive the Peltier element " stated in below pictures ?
I need to design a Peltier temperature controller which is low noise and without interferences just like this product TEC1091 and why the PWM method to drive the Peltier will have power loss?
