Socket power failure troubleshooting usually uses the direct observation method and process maintenance method. The following introduces maintenance methods in combination with several circuit failure phenomena. Malfunctions in the socket power supply are almost all kinds. The most common faults are... read more
4. Overhaul of output ripple If the power outlet fails periodically, the problem is often too much loss in the outlet. If the snubber circuit has been used, check whether it works normally. The working principle of this buffer circuit: when the transistor is turned off, the voltage of the C pole inc... read more
