    Tips: Troubleshooting the interrupted DC output and unstable voltage output of switching power supply

    If the power fuse remains in perfect condition but there is no DC output at various levels in loaded condition, it may be caused by open circuit, short circuit, overvoltage, overcurrent, failure of auxiliary power supply, failure of oscillating circuit, over load of power supply, breakdown of rectifier diode in high-frequency rectification and smoothing circuit, or electric leakage of smoothing capacitor. If voltage output remains zero after checking secondary components by multimeter and clearing breakdown, overload or short circuit of high-frequency rectifier diode, it can be confirmed there is problem with control circuit of power supply. If there is voltage output at some parts, that means the onboard circuit works properly and it is problem of high-frequency rectification and smoothing circuit. High-frequency filtering circuit mainly uses rectifier diode and low-voltage filtering capacitor to output DC. If the rectifier diode breaks down, the circuit will be unable to output voltage. In addition, electric leakage of filtering capacitor results in unstable voltage output. Damaged components can be found out by checking relevant parts with a multimeter.
