types of uninterruptible power supply

is closely linked with the working electromagnetic environment. If the EMS capability of parts is too low, if the components are subject to internal or external electromagnetic harassment, the light may affect the product performance, or the heavy parts may directly affect the vehicle safety, resulting in personnel damage. Because vehicles and their parts have very high safety performance requirements, the vehicle's EMC standards are often more severe than the average number of electronic produ

stable working state. Next, we will analyze in detail the transition process of the switching power supply at the start time. In Figure 1-19, when the active switch is switched from power-on to power-off, the back-EMR generated by the secondary Coils of the switching power

1.1 Types of switching power supplies1.1.1 Linear regulator, the so-called linear regulator, which is what we say the Ldo, generally have two characteristics:? The transmission element works in the linear region, it does not have a switching transition;? For buck conversions only, you will rarely see the boost application.1.1.2 Switching Regulator? Transmission device switches (FET), fully connected and com

If you use your mobile phone with the data line charge can not be charged, please replace a can only charge can not transmit data microUSB line to try, this may be mobile charger in the electricity transmission to the phone. You can try to connect other phones to the mobile power supply to see if there is a situation where the electricity can not be recharged into the phone, and if not, it could be a phone

I. Effect of Temperature on the performance and life of Communication Switching Power Supply The main component of the communication switching power supply is the high-frequency switching rectifier, which gradually develops and matures along with the development of power ele

Some external factors can cause the switch to not work properly, such as external power supply instability, power line problems and so on. It will also cause damage to the internal parts of the switch due to power problems. If the power led on the switch is green, everything

fire extinguishers should be used when electric equipment is on fire. foam fire extinguishers should not be used to extinguish the fire. 10. Commonly Used DC power supplies in substations include battery, silicon rectification, and Capacitor storage. 11. The lighting of substations (sites) must be an independent power supply and cannot be mixed with common light

Q: What is the difference between a frequency conversion power supply and a frequency converter? I believe everyone has many questions. I only know that the frequency conversion power supply is not the same product as the frequency converter, but I don't know much about it, some friends may know that the inverter is us

Frequency Power Supply that cannot be touched by the human body from the front. It is applicable to the screen, disk, and rack installed in the electric control cabinet or in the electric room, high requirements on the installation environment.The above are several types of methods for installing the protection structure of the variable frequency

1. Overview of three types of non-isolated DC-DC topologies 1.1Buck type converter The buck converter topology is shown in Figure 2.2 and the buck Converter is also known as a buck-type power supply topology. When the switching tube s is on, the diode VD negative voltage is higher than the positive reverse cutoff, at which time the current is fed through the in

the mobile power after when it is incorporated, the USB charging line is connected directly to the input and output interface of the mobile power supply, although the short circuit protection is used in most of the products, but it is very dangerous to connect the positive and negative pole of the electric core directly. Once the protection circuit has failed, i

Switching power supply Control mode Switching power supply in normal operation, the load in the external interference will produce fluctuations, how to ensure that the load fluctuations in the condition of the output stability needs to control the knowledge of the theory to solve. In the design of switching

Enterprise Data Center is now more and more important, how to ensure the stable operation of enterprise data Center has become a key factor, UPS is currently a lot of enterprises in the data Center standard accessories, then how to choose a suitable enterprise application of UPS power. categories of UPS In general, the UPS system is divided into three categories, for back-up, on-line interactive and online. Different vendors will provide different co

Full-Power UPS power Battery (lead-acid battery), not connected to any load (equipment) vacant about six months after the battery must be recharged to avoid damage to the battery. A battery with a load discharge to a low electric state must be recharged within 72 hours after the battery is discharged to avoid battery damage. UPS power

The following is my summary of the basis of the mos and MOS driving circuit. I have referred to some materials, not all original. This includes the introduction, features, drivers, and application circuits of MOS tubes. When using MOS to design a switching power supply or motor drive circuit, most people will consider the mos on-resistance, maximum voltage, maximum current, and so on. Many people only consi
