Abstract :
In order to solve the problem of precise temperature control, the thermoelectric cooler (TEC) principle widely used is analyzed for the design of the whole control process and selection of control parameters, and then accurate simulation model of the TEC is established in Proteus simulation software. Moreover, combined with the traditional circuit simulation model, the temperature control loop is designed, and the response characteristics of the system are tested using an input signal similar to the unit-step function to achieve the precise temperature control. Simulation results show that the proposed control circuits can precisely convert error signal to output voltage sent to TEC model, and TEC model behaves approximately like a two-pole system. The first pole starts at 20mHz and a second pole at 1Hz.
