  Summer is coming, and the weather is getting hotter and hotter, but it is not only us who are afraid of heat, but the power adapter is also very afraid of heat. When the temperature of the power adapter is too high, the function of its internal components will be affected, resulting in instability the elements of. Therefore, general power adapters need overheating protection. What are the main types of overheating protection for power adapters?

  The overheating protection types of the power adapter can be divided into the following categories: automatic reset type, manual reset type, non-renewable, non-resetable type and various other types that can provide equivalent thermal protection

  The heat sources of the power adapter are mainly Schottky rectifier diodes, high-frequency switching transformers, power MOS tubes, and filtered electrolytic capacitors. The temperature rise of power MOS tubes, high-frequency transformers and rectified Schottky diodes is relatively prominent. In order to prevent the power adapter from being damaged due to overheating, the design of the power adapter not only requires the use of electronic components with good high temperature characteristics, but also requires the printed PCB board, heat sink, high-frequency transformer, etc. to have reasonable design, advanced production technology, and need to take overheating protection. These are the conditions that must be met in order to ensure safety.

  In order to suppress the temperature rise of the power adapter, in addition to selecting the power MOS tube with small leakage current and short storage time, it is also necessary to add a heat sink to the power MOS tube. After the MOS tube is equipped with a heat sink, the stability of the power adapter will be greatly improved, and the loss rate will be significantly reduced. The function of the electronic switch overheating protection measures is to cut off the AC input line of the power adapter, or forcibly turn off the modulated pulse output before the temperature of the components or the power supply shell that are prone to heat in the power adapter exceeds the specified limit value, and stop the high-frequency oscillation.

  The temperature resistance and fire resistance of the power adapter are not only directly related to the reliability and service life of the power adapter, but also directly related to the risk of fire and the safety of users' lives and properties, so as a power adapter manufacturer Product safety is taken very seriously. The safety of such products should also be an issue that all power adapter manufacturers must pay attention to.
