What does a vehicle module power supply look like?(5)

The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .

Regardless of how much control the product material and production process are, aging needs to be checked. Because the incoming inspection of electronic components and transformers is difficult to control, the quality stability of this batch of power supplies and whether the materials are detected to have potential safety hazards can only be detected through aging and high-temperature sampling of the entire batch of power supplies.
