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 stabilit
1-4-3. Calculation of energy storage inductance of the parallel switching power supplySimilar to the numerical method used to calculate the energy-saving inductance in the inverted series switching power supply, the energy storage inductance of the parallel switching power supply is also analyzed starting from the critical continuous current state of the current
If the power plant outputs "clean" high-quality power supply, but the power supply passes through transmission and distribution, it is affected by the damage caused by weather, user equipment, and human factors, power supply quality problems such as voltage overshoot, drop, interruption, and common mode noise are quite

What is power consumption testing?
(1) Concepts
A Linear Power Supply typically samples the output voltage and sends it to the Compare voltage amplifier with the reference voltage. The output of this voltage amplifier serves as the input of the Voltage Adjustment tube, it is used to control the adjustment tube so that its junction voltage changes with the input, so as to adjust its output voltage. However, the switching power supply changes

Basic Knowledge Reserve ChapterThe related operations of matrices are then learned in linear algebra.1.1 Definition of the matrix:? N-order matrices (n-order matrix): a matrix with the same number of rows m as the number of columns N, as shown in a 4-4 Phalanx: *Row matri
Computer power-on automatic power off problem
1, check the motherboard on the capacitor is not a bulge phenomenon, if there is, you need to replace the capacitor.2, if not, it is estimated that your computer power output power is not enough. Computer shutdown after a period of time, startup difficulties or startup pro
The fast power algorithm can be said to be a kind of ACM competition is necessary, and is also a very basic type of algorithm, given that I have been learning more fragmented, so today with this post summed upFast multiplication usually has two types of applications: First, integer operation, calculation (A*B) mod C second, matrix fast multiplicationinteger operations: (Fast multiplication, fast power)Let's
Power query and power map are the new Excel-oriented functions released by Microsoft on the WPC recently. With these two features, self-help BI makes it easier for you to discover and process data and enrich the data visualization functions.
The predecessor of Power query and power map are data explorer and geoflow, bo
1-4-1. operating principle of the parallel switching power supplyFigure 1-11-A is the simplest working principle of the parallel switching power supply, and Figure 1-11-B is the waveform of the output voltage of the parallel switching power supply. In Figure 1-11-A, the UI is the operating voltage of the switching power
5G technology, the power consumption and cost problems of far-reaching optical power supply are enough for it to drink a pot, 5g a pot
5G is getting closer and closer, but not all places have it, and it will not be abrupt. The first version that comes to people's eyes is not the fastest version of the technology. In reality, 5G is the first to show in a densely populated metropolis. Since 2020 or 2021, 5g
function image of power output power of geometric artboard How to make ?
First of all, to understand the power output power and the relationship between the external resistance: set the power of the electromotive force is e, internal resistance is r, outside the resistance
Chassis power supply as a source of computer energy, its importance is more and more people pay attention to, but, the importance of power supply fan is still neglected by most consumers. As a result, a sudden increase in the noise of the power supply fan has occurred. The reason is that because the fan is running all the year round, the fan blade and the fan's e
Computer power-on automatic power failure One:
The specific situation is like this: turn on the power switch, press the power-on button, the fan turned, the machine has movement, after a power outage, the fan does not move, the light is not bright, and then pres
1-2-3. Calculation of energy storage filter inductance of tandem Switching Power SupplyFrom the above analysis, we can see that the output voltage of the tandem switch power supply is related to the duty cycle D of the control switch and the energy storage inductance L, because the energy storage inductance L determines the current rise rate (DI/dt), that is, the output current size. Therefore, it is import
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
Power View is a tool that enables you to create dynamic, interactive reports, and supports a rich variety of chart types, and reports created in power view can be easily shared and used by users who view reports to interact with the Power View report. Starting with this one, Anna will make a dynamic report in power vie
1. Fast power is the n power of fast calculation base. Its time complexity is O (log₂n), and the Simplicity of O (N) compared to the efficiency has been greatly improved.
Usage: Used to solve the B-side of a, and B is a very large number, and the complexity of O (n) times out. Then we need this algorithm, note that it can not only be the logarithm of the
