plan for the video card is "Maximum battery life", the processor is thermally passive, the minimum processor state is "0%", the maximum processor state is "100%", and the screen brightness is 40% when the battery is switched on, and the power supply is 100%. Energy-saving mode is more suitable for mobile office use, all hardware in the state of the lowest power consumption, is the minimum consumption of electricity mode, so the lowest heat dissipatio

Computer in the process of use, often appear more strange faults, such as panic, program error, speakers have a murmur. Hard drive format, reinstall system, can not solve the problem. This problem should be a problem with the hardware. You can use the substitution method to check that the quality of the power supply is important. If the quality of the power supply is poor, it will cause a variety of

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 power supply applied to the control mode mainly divided

source is compared with the ideal excitation source:Increasing the equivalent resistance of the series resonant circuit and reducing the parallel equivalent resistance in the parallel resonant circuit. The consequence is to reduce the quality factor of the resonant circuit. In order to make the Q value of the resonant circuit not affected by the signal source resistance excessively, the resonant impedance of the series resonant circuit is only suitable to work with the low internal resistance s

product must be properly applied. Therefore, the following circuit is the correct method in the design: Figure 1 a210 Power Supply Diagram The external voltage 5 V is sent to switch sw2 through D2, and the charging management IC mcp73831 is sent to the lithium battery. The left-side voltage of sw2 is 5 V-0.7 V = 4.3 v. The voltage of the lithium battery is less than 4.3 V at the left of sw2, regardless of whether it is fully charged or not. So d1 is

Although the various advantages of the Frequency Conversion Power supply can be widely used in various industries, the frequency conversion will generate a kind of Power Harmonic that has some harm to the machine equipment during operation. What kind of harm will this harmonic wave cause to peripheral electrical equipment? The technicians at Yangsheng zhonggang have sorted out some electric harmonic waves of Variable Frequency elements for you to do s

With the development of information technology, data centers and network data centers are becoming increasingly large. However, the Power Distribution Unit PDUS that carry the operation of equipment in the data center are often ignored by equipment purchasers in the data center. For a long time, due to the lack of similar products, many integrators or users can only use civil plug-ins for replacement, it does not meet the safety requirements of Cabinet electrical indicators in terms of load curr

The resonator is formed between the power supply and the large plane of the formation. When the high-speed digital signal passes through, it is like a speedboat setting up a wave on the lake, and the voltage between the power supply and the ground fluctuates. Since it is a resonance (mechanical resonance), it requires a natural frequency, which is related to the shape of the power

Many enterprises, factories and other customers have been using the inverter power after buying it back, and will not perform maintenance on the power without using the inverter power supply, maintenance and so on, because doing so will lead to the short service life of the inverter power supply, how can we avoid these problems?Yes, it is regular maintenance of the power

1. DSP6000 power-on sequence Problems DSP is indeed a freak. Two common problems are: (1) unable to connect to the CCS development environment; (2) burning chips. I am using TMS320C6713 now. The following experiences are based on DSP6000. Other series may be different. It seems that the performance of the chip has changed, and the chip has never been burned. However, CCS still often cannot be connected. Some of the reasons are related to the stability of the hardware. When designing the power

Powerbus Technology Powerbus is a power bus technology that is the only bus technology in the industry that can support high-power load power and high-speed communication, compared to other power-supply bus technologies: ①powerbus power supply efficiency, through the two power cord maximum can provide a single device 1 a power supply capacity, the bus can provi

Wind energy, solar energy, and other alternative energy sources receive a good return on investment. If the data center manager has a golden rule, it is: Do not toss your power supply.For almost all data centers, their power supply is AC. AC is not only suitable for a single PC in the study, but also for data centers with a large number of servers. The US Environment Protection Agency predicts that the energy demand for data centers will double in t
