· What are the reasons for intermittent oscillations in switch mode power supplies?

Switching power supply is a type of power module. He is also a very common type of power supply, and the reason for adding the word "switch" is because its internal structure has a Schottky diode with switching characteristics. This diode has a high switching frequency and can quickly switch off thousands of times in a short period of time. And each time, it can provide power and current output, which plays an important role in general integrated circuits. However, in the use of Switching power supplies, intermittent oscillations may sometimes occur. What are the reasons for this? Next, Kinri will provide a detailed introduction to this issue for everyone.The reasons for intermittent oscillation in switching power supplies can be divided into three types: overload type, undervoltage type, and no-load type.1. Overload typeThis type of fault is more common among the four types of faults. Usually caused by breakdown of the rectifier diode on the secondary side of the switching transforme...

· Analysis of the Causes of Burnout of Switching Power Supply

Switching power supply is currently one of the most widely used power supplies, but it often burns out during use. If these problems are not solved, it will not only cause waste of electrical equipment, but also affect the efficiency of use. Below we will analyze the reasons for the burnout of the switching power supply:1. Soft start circuit failureThe soft start circuit is the process of applying voltage to various components before switching on and off the switching power supply. If there is a problem with the soft start circuit, it is easy to cause overcurrent, which can lead to burning out the switching power supply.2. Switching tube integrated circuit board anti peak absorption circuit failureThe anti peak absorption circuit is generally composed of diodes, inductors, etc. If it fails, it is easy to cause the anti peak voltage to exceed the withstand voltage range of the switching tube, leading to short circuit and burning of the switching tube.3. Positive feedback is too strongT...

· These four types of household appliances will not only consume electricity without unplugging, but also affect their service life

Household appliances are an indispensable part of modern life, bringing great convenience to our lives. However, in the process of using household appliances, we also need to pay attention to some details, such as the issue of not unplugging the plug. Some household appliances, if not unplugged, not only consume electricity but also affect their lifespan. Next, let's take a detailed look at the problems caused by not unplugging these four types of household appliances.Firstly, what we want to talk about is the television. A TV is one of the most common household appliances, but if it is not unplugged and left on standby for a long time, the TV will remain in a low-power state and consume a lot of electricity in the long run. In addition, long-term standby of the TV can also cause an increase in the internal temperature of the TV, accelerate its aging, and thus affect its service life.Secondly, air conditioning is also one of the household appliances that cannot be unplugged. Many peop...

· Why do household appliances still consume electricity after being turned off?

If you pay a little attention in daily life, you will find that although all the appliances at home are turned off, they still consume a certain amount of electricity. Why is this? This article will take you to understand.1. Misunderstandings in life: turning off appliances will eliminate power consumption. Is this viewpoint correct? If you only turn off the appliances and leave the plug unplugged, it will still drain the battery. Which appliances still consume electricity without unplugging?2.After the electric kettle, oven, and bread are turned off, they will not consume electricity. Everyone can exclude them.3. After using the range hood, if the standby power is 2.2W without unplugging, is it almost impossible to unplug the power plug of the range hood in daily life?4.Although the standby power of the microwave oven is only 1W, the accumulated losses over time are also significant.5. Are you used to unplugging the rice cooker after using it? Anyway, I used to not unplug it often, b...

· What is a switching power supply?

Switching power supply is a common power supply device widely used in various electronic devices. So, what is a switching power supply? This article will explain the definition, working principle, and advantages of switching power supplies from different perspectives.1. Definition of Switching Power SupplyA switching power supply is an electrical device that can convert alternating current into direct current and regulate the current through switching components. It converts the power supply voltage into a stable DC voltage, providing power support for the normal operation of electronic devices. Switching power supplies are commonly used in fields such as computers, communication equipment, industrial automation, and medical equipment.2. The principle of switching power supplyThe working principle of switching power supply is mainly divided into two stages: energy storage stage and output stage. Firstly, during the energy storage stage, the AC power supply is rectified through a recti...
