Zusammenfassung:	The utility model discloses a TEC control circuit. A controller is respectively connected with a DC power supply, a thermistor, a first switching device, a second switching device, a third switching device and a fourth switching device. The output end of the DC power supply is connected with the first end of the first switching device and the first end of the second switching device. The second end of the first switching device is connected with the first end of the third switching device; the second end of the second switching device is connected with the first end of the fourth switching device; the second end of the third switching device and the second end of the fourth switching device are respectively grounded; the TEC module and the thermistor are connected in series and are connected in series between the second end of the first switching device and the second end of the second switching device. According to the TEC control circuit provided by the embodiment of the utility model, the cost can be reduc
