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.

Cooling technology has developed rapidly in recent years, significantly improving efficiency and reducing energy waste. The energy consumption of the air conditioning in the computer room accounts for 1/3 to half of the total power consumption of the data center. Nevertheless, these measures are not enough. Another key element of data center infrastructure provides similar improvements.

Uninterruptible power supply is an important part of data center operation, providing key power protection and providing reliable backup power when the power interruption occurs. But just as servers consume electricity, generate heat, and require continuous cooling to run safely, so do UPS devices. In the past, this has affected the efficiency of many data centers, but in this field, significant technological advances have been made, that is, the rise of modular UPS systems. Previously, the most deployed UPS power source in the data center was a large tower type device, using traditional technology to achieve the best efficiency only when the workload was 80%-90%. This UPS device tends to be easily deployed at initial installation to provide the necessary redundancy, which means that they often run under low load, it is inefficient and waste a lot of power. In addition, these large tower UPS also draw a lot of heat, so a lot of cooling is needed. However, the UPS power supply has a service life, and the industry’s best practice suggests updating equipment every 7-10 years. Many of the UPS installed and deployed during the boom period of the data center will be replaced when the modern modular UPS is introduced. These UPS power supplies can provide higher efficiency, simple scalability, intelligent control, and system interconnectedness.

The modular UPS system is not a large, inefficient, independent tower type device, but consists of several smaller rack mounted units that are connected in parallel to provide the necessary power and redundancy. Its capacity is closely matched with the load requirements of the user’s data center, and can be easily extended at any time when it is extended, and other modules can also be simply added on the basis of “pay on demand”. Modular UPS does not contain transformers, which itself can provide up to 5% efficiency improvement. Its load curve efficiency is as high as 96%, which is far beyond the function of low power UPS. In theory, running modularized UPS systems in economic mode can even increase their efficiency to 99%, but this performance enhancement requires the key load to face the risk of grid power fluctuations. Modular UPS devices are smaller, lighter, and produce less heat, so there is no need for too much cooling equipment, less space and easier maintenance. In addition, its modular design is “hot plug”, so if there is a module failure or failure, they can be replaced without the power protection system online. This kind of UPS power system is also easy to integrate with the energy management system (EMS) or data center infrastructure management (DCIM) software to help automate the data center. These intelligent UPS devices continuously collect and process running data, which can be used to optimize performance and identify future areas of improvement, which means that the pursuit of maximum efficiency is a continuous process.

By providing higher power density and higher efficiency with smaller area, modularized UPS enables the data center to do much more with less money. In an era of increasing demand for data, overloaded power grids are becoming more and more overwhelmed. This capability will be invaluable. The use of an efficient UPS power can do this while reducing energy costs and reducing carbon emissions.

2.The telecommunication power industry needs to be fundamentally rectified.
3.Serious pollution of lead-acid battery.
4.The power equipment occupies a large area, and the space is wasted seriously.

Development trend of industrial chain

1.Energy saving and environment-friendly energy storage equipment will be the best.
2.The efficiency of the telecom power supply “ceiling effect”.
3.Domestic industry is also developing gradually.
4.The development of telecom power supply to high voltage.
