Digital control system using a thermoelectric cell for temperature electronic devices testing

This paper presents a temperature digital control system for performance evaluation of electronic devices under different operating temperatures. The system is based on a thermoelectric module of Peltier effect, which is used for heating or cooling the device under test (DUT). A digital PI controller is designed through simulations with an electric model of the structure, developed in Simulink^®. Based on the parameters and results from simulations, the controller is implemented in Labview^® and experimental results are obtained using a servo amplifier like actuator.
