In our daily life, the small appliances and small appliances that we use every day sometimes have short circuits, poor contact, burned fuses and other faults. At this time, some friends who have some knowledge of power supplies and are relatively clever can fix them by themselves. Got a lot of trouble, how to solve if your PD power adapter fails.
Let's take a look at some of the possible failures of the power adapter
1. Line failure: including the power cord is damaged and not energized, the contact port is oxidized and the contact is poor. Solution: Focus on checking whether the input line and output line are energized. If the line is faulty, it can be solved by replacing the power cord.
2. Output voltage is too low: switching power supply load short-circuit failure (especially DC/DC converter short-circuit or poor performance, etc.), at this time, first disconnect all loads of the switching power supply circuit, and check whether the switching power supply circuit is faulty or the load circuit is faulty. malfunction. If the load circuit is disconnected and the voltage output is normal, it means that the load is too heavy; or it is still abnormal, it means that the switching power supply circuit is faulty.
3. The fuse is burned out or blown out: check the rectifier bridge, the diodes, the switch tube, and the large filter capacitor on 300 volts. It may cause the insurance to burn and turn black, or it may be caused by a problem with the anti-interference circuit. Special attention should be paid to the fact that the fuse is burnt due to the breakdown of the switch tube, which usually burns the power control chip and the current detection resistor. The thermistor is also easy to burn out along with the insurance.
The above are the problems that may occur when the PD power adapter is in use. Hope it can help you.
