The current production of computer motherboards are using switching power supply mode. Switching power supply mode can be divided into: single-phase power supply, two-phase power supply and multiphase power supply.
(1) Single-Phase power
In many of the existing supplies, continuous ink supply system is one of the most controversial. Because of its low price, so by some profit for the purpose of business output users favor, the original cartridge and the same as the system, there will be problems. Just because the connection system is likely to bring some drawbacks, it is relatively troublesome. Therefore, the choice of the system should pay attention to quality, ink is particularly im
Power supply is a computer's "power Core", is also prone to failure of one of the components, the failure of the manifestation of a variety of forms. For example, after power-on memory parity error is often related to power, but users are generally easily mistaken for computer memory failure, can not connect with the power. In fact, once the power supply does not provide the normal operating voltage, the me
Stabilized Voltage Supply is an electronic device that provides stable AC power or DC power for the load. Including AC and DC regulated power supply.Necessity of using regulated power supply:With the rapid development of society, electricity equipment is growing day by day. However, the aging and development of power transmission and distribution facilities are lagging behind, and the end user voltage is too low due to poor design and insufficient pow
3C Certification
Of all the power supply, only one power supply has not passed the 3C certification, of course, you can not buy in the market, because the power supply in our market, must pass the 3C certification, the power is not certified the application, waiting for certification a hand, it could be put on the market. This means that in the 3C certification
If the CPU is a strong heart of the computer, then the power is its energy center. The power supply is not valued by the users in PC computer, but it is the product that is often neglected, but it provides stable and continuous current for all computer equipments, such as CPU, memory, optical drive and so on. If there is a problem with the power supply, can not provide energy to other parts, it will affect
RFID is revolutionizing the inventory tracking method in the supply chain. This technology ensures that the right products reach the customer's hands as needed and that the inventory of the distribution center is controlled at the optimal level.For manufacturers, RFID technology is bringing about labor savings and operational efficiency improvement, thus increasing the operating income of the entire production line and distribution process. Manufactur
The basic function of the power supply in the computer is to convert 220V alternating current into the low-voltage DC power required by the computer, generally it is difficult to see the effect on the performance of the whole machine intuitively. But as a source of power, power supply is actually the basis of stability, if the power quality is not high or insufficient power, but at the same time to drive m
Fault model: Gold Great Wall c-i5271-type display;
Fault reason: lightning;
Failure phenomenon: no display. Users reflect that the machine was struck by lightning, issued a "bang" a sound.
Analysis and overhaul: Open the chassis found that the power fuse (f901/3.15a) has been burned, and the internal blackening, indicating that the power supply has a serious short-circuit failure. The power supply adjust
1-6. Switch Power Supply of excited TransformerThe transient control characteristics of the output voltage of the switch power supply and the load characteristics of the output voltage are relatively good. Therefore, the operation is relatively stable, and the output voltage is not prone to jitter, it is often used in scenarios with high requirements on output voltage parameters.1-6-1. Working Principle of
If the CPU is a strong heart of the computer, then the power is its energy center. Power in the PC computer is not the user's attention, but it is this often overlooked product, but for the CPU, memory, optical drive and other computer equipment to provide a stable, continuous current. If the power supply is out of the question, it can not provide energy to other accessories, it will affect the normal operation of the computer, and even damage the har
Today, the advanced planning scheduling system has become one of the hottest topics in supply chain management. APS uses some complex mathematical operations to process some variables, making supply chain optimization a reality.
Today, optimization technology has become a key tool in enterprises' decision-making to increase their competitive advantages. Perhaps, for optimization technology, the most widel
power of the Reverse type transformer is output and the current flowing through the secondary coil circuit.
Figure 1-20 is the switching power supply of the anti-Exciting Transformer. When operating in the critical continuous current state, the input voltage of the rectification is UO, the load current IO, and the magnetic flux of the transformer core, and transformer initial and secondary current waveforms.Figure 1-20-a), the output voltage of t
We know that the rated power of the small power supply is difficult to meet the system demand, light is the crash frequently, heavy can not boot or even damage the hardware. Because of this obvious consequence, consumers often pay attention to power supply only when they buy power, ignoring other aspects.
In fact, now buy power has not been a single focus on the rated power, but also should be in the power
Assemble the computer process of the friend will tend to the power of the cold, like to focus attention to the processor (CPU) and independent graphics, memory and other major computer components, and often on the power is not how to care, which is the most easily in the power to obtain more profits in the reason, The stability of computer power supply is directly related to whether the whole machine can operate stably and whether it can work properly
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 electronics theory and technology and power electronic devices. With the soft switch technology, the power consumption becomes smaller, th
