How to observe fault phenomena and determine the cause of abnormal output voltage of power adapter

September 27, 2024
Observe fault phenomena to determine the cause of abnormal output voltage When the output voltage of an AC-DC power adapter is abnormal, some fault phenomena can be observed to initially determine the cause. If the power adapter cannot output the required power, it may be due to a fault in the power adapter itself, such as damage to internal components, loose line connections, etc.; it may also be due to the disconnection or damage of the connection between the power adapter plug and the battery; or it may be due to unstable input voltage or exceeding the limit of the power adapter. If the output voltage is unstable, it may be due to damage or aging of the power adapter capacitor, or poor contact of the power adapter transformer winding.
AC DC Power adapter
If the output voltage is too high or too low, it may be due to aging or damage of power adapter circuit components, or excessive load current of the power adapter, or a fault in the power adapter output voltage regulator. If the power adapter overheats, it may be due to poor internal heat dissipation of the power adapter, or a short circuit or excessive load of the power adapter.
