Research on Adaptive Switching Power Supply Control Technology

In view of the power supply damage caused by overheating of power devices, this paper proposes a switching power supply whose output power can be adjusted according to the operating temperature. The power supply adds a temperature and power monitoring unit and an output current control unit to the conventional switching power supply technology, and uses the monitoring units to test the operating temperature and input-output power of each power device in the system, and analyzes the relationship between temperature rise and loss. The relationship realizes the diagnosis of the state of the switching power supply, and reduces the temperature by reducing the output current and reducing the loss of the power source with hidden troubles, thereby achieving the purpose of extending the life of the power supply and improving the reliability of the power supply network.
