· What is the reason why the output voltage of a switching power supply is lower than the standard voltage?

In the field of switch mode power supply technology, people are developing related power electronic devices and switch frequency conversion technology at the same time. The two promote each other, and switch mode power supplies are expanding towards the direction of light, small, thin, low noise, high reliability, and anti-interference with a growth rate exceeding two digits every year. However, in the use of switching power supplies, sometimes the output voltage may be lower than the standard voltage. What is the reason for this?480W Din Rail Switching Power SupplyThe reason why the output voltage of the switching power supply is lower than the standard voltage:(1) The occurrence of this situation in the switching power supply of the new device may be due to poor output power. The power of the selected power source should be sufficient to avoid the phenomenon of "a small horse pulling a big cart"; It is also possible that the output of the power supply does not meet the design specif...

· Internal and external interference of power adapters

The interference of power adapters is generally divided into two categories: first, the interference formed by internal components of switching power supplies; The second is the interference caused by external factors in the switching power supply. Both involve both human and natural factors.65W Desktop Power AdapterInternal interference of power adapter: The EMI generated by switching power supply is mainly caused by high-order harmonic current interference generated by the basic rectifier and peak voltage interference generated by the power conversion circuit.There is a distributed capacitance between the switch tube and its heat sink, the casing, and the leads inside the power supply. When the switch tube flows through a large pulse current (generally a rectangular wave), the waveform contains many high-frequency components; At the same time, the device parameters used to turn off the power supply, such as the storage time of the switching power transistor, the large current of the...

· Differences and usage scenarios of shell type, rail type, and open frame type power supplies

In the field of electronics, power supply is a crucial component, and among them, shell type, rail type, and substrate type power supplies each have unique characteristics and application scenarios.Shell type power supply400W Switching Power SupplyLet's first talk about the shell type power supply, which is like a steady "Hercules". It has a sturdy casing, which not only provides good protection for internal components, but also ensures stable and reliable power output. Its heat dissipation performance is often excellent, and it can maintain good condition during long-term operation. It is often used in large equipment that has high requirements for power stability.Rail type power supply120W Din Rail Switching Power SupplyNext is the rail type power supply, just like a flexible "craftsman". It can be easily installed on standard rails, and this unique design makes it extremely convenient for installation and maintenance, saving a lot of time and energy. Especially suitable for industr...

· What is overvoltage protection for power adapters?

In the event of a malfunction, the output voltage of most power adapters may exceed the specified or required value. In power adapters without protective circuits, high output voltage may cause damage to internal or external devices of the power adapter. In order to protect the power adapter device in such abnormal working conditions, a common method is to add an overvoltage protection circuit to the power adapter.Because TTL circuits and other logic circuits are easily damaged by overvoltage, providing overvoltage protection for the output of such circuits has become a common practice in industrial applications. As for other output voltage protection functions, they are usually added according to the needs of the system engineer or user.5W MODEM POWER ADAPORTypes of overvoltage protectionOvervoltage protection technology can be roughly divided into the following three categoriesType 1: Simple thyristor overvoltage protection.Type 2: Overvoltage protection based on voltage clamp techn...
