Description
technical field [0001] The invention relates to the field of control of semiconductor refrigerators, in particular to a temperature control circuit of a superluminescent light-emitting diode. Background technique [0002] The traditional semiconductor refrigerator TEC is made by semiconductor Peltier effect. TEC uses some N-type P-type semiconductor pairs, which are connected together through electrodes and sandwiched between two ceramic electrodes. When a current flows through the TEC, the heat generated by the current will be transferred from one side of the TEC to the other. , A "hot" side and a "cold" side are produced on the TEC, which is the heating and cooling principle of the TEC. Depending on the direction and magnitude of the current, the TEC will produce heating or cooling effects. Therefore, TEC has a very wide range of applications such as temperature control of lasers. [0003] However, the traditional semiconductor refrigerator TEC control equipment also ha...
