TEC controllers are used for thermoelectric cooling and heating in combination with Peltier elements or resistive heaters. Peltier elements are heat pumps which transfer heat from one side to the other, depending on the direction of the electrical current. TEC controllers are used to drive the Peltier elements.
This system design guide provides information about how to design a simple thermoelectric cooling application using TEC controllers and Peltier elements. When designing a thermoelectric application, cooling is the critical part. So, we will take the case of cooling an object as example for the design guide.
