After hundreds of years of development, the 48V power supply structure in the telecommunication industry has become very standard and universal. The industrial chain and ecology are very mature, so that most of the network equipment can directly support the 48V DC power supply. Even before the data center industry tried to use the 48V power supply architecture, but the traditional way is to learn from UPS to put 48V power and batteries in the power room and battery room of the data center. The problem caused by this method is that the traditional server equipment often lacks the power to support 48V input directly, and the 48V power supply brings about the power line investment, transmission line voltage drop and transmission line loss when the low voltage and long distance transmission. Finally, the traditional 48V power supply technology can not be carried out in the data center industry. But with the development of the whole cabinet technology, and the pursuit of low cost and high efficiency, direct power supply technology, high-power cabinet and lithium battery technology, the use of distributed near the cabinet or even cabinet built-in 48V power supply structure will be an important direction of future development.

The functions are different, the voltage regulator and the UPS uninterruptible power supply are widely used, but there is a difference between the regulator and the UPS power supply, and many people are always wrong to think that the regulator is the UPS. So, what is the difference between UPS and voltage regulator?

 

UPS power supply is divided into an online UPS power supply and a backup UPS power supply. The common computer is equipped with a backup UPS power supply. The backup type including the voltage stabilizing part, which adopts the relay shift voltage regulation mode, and the voltage stabilizing effect is very poor, so it can not calculate the voltage stabilizer.

 

When the online UPS power supply is working, firstly convert the city into DC to charge the UPS battery, and the inverter turns the DC power into alternating current to power the load. As the city electricity passes through the exchange process to the DC, and then to the AC, the original interference and pulse voltage components in the city electricity have been filtered very clean. Therefore, the voltage of the online UPS power inverter is very stable. The advantages of high frequency UPS are small size, light weight, high efficiency, and its disadvantages are poor resistance to overload and impact. Low frequency UPS power supply is better, but bulky and expensive.

 

The regulator is designed for the instability of the grid voltage, mainly for the protection of the back-end equipment, and the protection function of the equipment is relatively perfect. In general, large UPS power supply must also be equipped with a voltage regulated bypass system (voltage regulator). The voltage regulator has a wide range of application, which can be used in almost any place where electricity is needed (the premise is voltage instability). Generally, the home can choose high-precision full automatic voltage stabilizer, and the price is also cheap. If it is used in industry, then use high-power compensation AC voltage stabilizer, there are mechanical and electronic type. General electronic type is not needed to replace carbon brush, simple and practical and convenient, but the voltage of the electric field is low, it is more reasonable to choose the mechanical regulator which can be manually adjusted. The voltage is adjusted manually to ensure the normal operation of the machine.

 

The above voltage regulator and UPS power supply are briefly introduced, in fact, the biggest difference is: The voltage stabilizer can only stabilize the voltage; UPS can not only play a stabilizing role, but also be able to continue power supply by battery inverter after power failure to ensure that the equipment does not power down.

After the development of battery energy storage, electric vehicle, consumer electronics and other industries, the maturity of technology and industry has increased rapidly in the past few years, and the security has been greatly improved, and the price has been greatly reduced at present. Considering its excellent discharge capacity, high temperature resistance, simple maintenance, high energy density and light weight, it is a hot research field in many industries, and it fits the application scene of future data center and can be used to replace the traditional lead-acid battery. Considering its long service life, the cost from ROI is similar to that of lead-acid batteries. 48V lithium battery BBU technology has a lot of research and application in telecom industry and battery module of electric vehicle. It is also mature, and there are many industries and technology, operation data and so on. If a 2U to 3U high 48V battery BBU is installed next to the 48V power supply enclosure of the entire cabinet, a stable 48V power supply to the whole cabinet and 5 to 15 minutes of battery preparation can be provided, which can bring about a great innovation in the data center power supply architecture. No longer need the traditional UPS investment, no longer need the power room battery room, no more wastage and waste on the UPS and low efficiency 12V power supply, can realize the cabinet level edge growth side investment, can realize the 48V power module on demand configuration, can realize automatic energy saving dormancy, can change the hard disk like hot plug to replace the power supply modules and battery BBU, etc., eventually achieve low cost, high efficiency, easy maintenance, manageable power supply.

In electronic circuits, many failures are caused by switching power failures, and most of the common failures of the switching power supply are caused by damage to some vulnerable parts. For example, the switch tube in the switching UPS is often damaged, but the switch transformer has a very low probability of damage, almost negligible. So I summed up some of the components which are easily damaged in switching power supply, and what will happen after the damage.

 

1.Protective tube
Most of the burning protective tube is caused by the large current of the post level circuit, that is, the circuit behind is short circuited, such as the switch tube, the current limiting resistance, the bridge pile burning the short circuit, the chip damage, the large filter capacitor damage and so on, all will cause the burning of the Protective tube, the failure phenomenon is no response to the electricity. If you change the protective tube, do not rush the electricity test, we must find fault or take some measures before the electrified.

 

2.Filter capacitor damage
Filter capacitor leakage or capacity reduction, will cause a crash or boot no response, filter capacitor damage generally visible from the capacitor drum can be seen.

 

3.Output filter capacitor
The fault phenomenon is similar to the filter capacitor damage.

 

4.Switch tube
In first point, the switch is damaged after the damage generally will be burned, the current resistance will follow the damage, and some time even PWM chips are also burned, but this phenomenon is not much. Since the protective tube has been burned, the fault must be energized and unresponsive.

 

5.Voltage regulator diode
In the case where the reverse voltage of the diode is greater than its nominal voltage, the regulator will reverse the breakdown, but this kind of breakdown can be recovered, that is, after the voltage is reduced, the regulator will break out of the breakdown state. If it is short circuited, then the regulator tube has been damaged, and the current exceeds the voltage regulator tube to withstand the current, resulting in thermal breakdown and is not recoverable.

 

6.Optical coupler and TL431
The damage of these two components usually causes unstable output voltage or no voltage output.

 

7.Starting resistance
The starting resistor is connected between the 300V power supply and the base of the switch tube. The damage of the starting resistor will cause 300V, but no voltage output, and the whole machine has no response.

 

8.Current limiting resistance
The resistance damage to the overcurrent protection circuit is the same as that of the starting resistor. 300V has no output voltage.

 

9.PWM control chip
PWM damage will cause 300V, but no output voltage can be repeated to burn off the switch tube and insurance, detection can be used to judge the ground resistance to judge its good or bad, normal to ground resistance to the ground, other pins are hundreds of ohms.
