[0002] A rectifier bridge is a circuit structure used to convert input alternating current into direct current for output, including full bridge and half bridge. A full bridge rectifier bridge usually includes four diodes connected at the end, and input or output pins are also provided at the connection part of the diode. During the diode rectification process, a large amount of heat will be generated. Working in a high temperature environment for a long time will directly affect the service life of electronic components, and even cause the circuit to burn out, resulting in safety hazards. Therefore, it is very important to monitor the temperature of the working rectifier bridge circuit, such as the content shown in the patent with the authorization announcement number CN215186476U. However, in the existing rectifier bridge temperature monitoring, the circuit for induction control and the rectifier bridge circuit are usually arranged in a housing, which has high requirements for the layout of components in the housing. In addition, the control circuit and the rectifier bridge are close to each other, which will also affect the induction of the working temperature of the rectifier bridge. Therefore, a temperature-controlled rectifier bridge structure that can accurately detect the working temperature of the rectifier bridge is needed. Summary of the invention
