Do switching power supplies burp like humans?

Do switching power supplies burp like humans? The answer is: Yes

In the operation of electronic equipment, efficient and lightweight switching power supplies have been widely used, and we often rely on a variety of switching power supplies.But in some cases, the switching power supply will actually make a strange burp sound.So why is it, what causes the power supply to hiccup during use?

There are several reasons for this:

1, capacitor problem: the capacitor in the power supply may cause voltage fluctuations due to aging, damage or poor quality, causing hiccups. This problem can be caused by evaporation or leakage of the electrolyte inside the capacitor.

2, inductance problem: the inductor in the power supply, if there is a short circuit, open circuit or damage, may lead to current fluctuations, produce sound.

3, power load problem: too large or sudden changes in the load may lead to unstable power output, produce sound. This is due to load changes caused by the power frequency adjustment is not timely.

4, temperature problem: High temperature may reduce the performance of the internal components of the power supply, resulting in abnormal sound. It may be that the temperature causes physical changes in the components or increases the internal electronic noise.

5, loose components: components inside the power supply, such as capacitors or inductors, if loose or poorly connected, may cause vibration and sound. This may be caused by prolonged operation of the equipment or an external shock.

The above problems may cause hiccups when the switching power supply works,We found that in the world of power supplies, every tiny component can have a significant impact on its performance.In the process of using the switching power supply, we should be vigilant and pay attention to the load, temperature, capacitance and inductance of the power supply to ensure that the equipment can run stably and efficiently.Through scientific and reasonable use and maintenance, we can better enjoy the convenience and efficiency brought by electronic technology.
