Power is like the heart of a computer, which plays a key role in stabilizing the power supply. As long as the power supply plug in, there will be work, even if not on, the internal standby power is still to work, so the computer power is also more prone to faulty hardware, especially some inferior power supply. Small series has been engaged in a year of power mai
The adjustment tube of the linear power supply is working in a magnified state, so the heat is generated and the efficiency is low (about 35%). A large heat sink is required, and a large power frequency transformer is also required, the transformer will be larger when multiple voltage outputs are to be made.The adjustment tube of the switch power supply is working in saturation and cutoff state, so it has a
Developers must understand the concept of switching power supply (features of the Power Supply Module) 1. Concept of switching power supply The switching power supply (Power Supply Module) is an energy converter. As a power supply

7.3 Supply Chain Management and Information Technology Application The definition of supply chain management can be interpreted: "supply chain management design, planning, implementation, management, monitoring and constantly optimize the supply chain operations to achieve innovative value and improve the enterprise'
(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
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 important to correctly select the parameters of the
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 prominent. Especially in industrial environm
1-2-2. Output Voltage filter circuit of the tandem switch power supplyMost of the output of the switching power supply is DC voltage. Therefore, the output circuit of the general switching power supply has a rectifying and filtering circuit. Figure 1-2 shows the working principle of the series-connected switching power supply with the rectification and filtering

1-2-4. Calculation of the filtering capacitor of the series-connected Switching Power SupplyWe also started from the current flowing through the energy storage inductor as the critical continuous current state, analyzed the charge and discharge process of the energy storage filter capacitor C, and then calculated the value of the energy storage filter capacitor C.Figure 1-6 shows the voltage and current waveforms of each point in the tandem switching power s
7.4 Supply Chain Management Thoughts 1Lean Production The essence of lean production is: give full play to the challenging creativity of people, constantly focus on the improvement of value-added processes, and strengthen collaboration with partners to meet the changing and personalized needs of consumers. It is embodied in the following aspects: 1)Embody the concept of value-added and eliminate all and non-value-added operations and activitie
-6-3-2. Calculation of parameters of the transformer of the excited switch power supplyThe parameters of the transformer of the excited switch power supply are mainly calculated from these aspects. One is the turns of the primary coils of the transformer and the volt second capacity. The larger the volt second capacity, the smaller the excitation current of the transformer. The other is the turns ratio of the Primary and Secondary Coils of the transfo
My motherboard is a 24PIN power interface, the power is 20PIN interface, compared, the more out of the interface is (+12V, +5v) and (+3.3v, GND) Two groups, now the motherboard only one +3.3v output used in the SATA power sockets, Want to use a large 4-pin socket to transfer into the 4-pin motherboard power connector, but the big 4PIN socket is (+12v, +5v, GND, GND), with one of the GND output instead of +3.3v can it? If not, consider using a large 4-pin to 4-pin motherboard power connector, OK?
seat plug. In flight power mode, the power consumption of the device must be less than 60 W. So in order to ensure flight safety, the power supply above 60 W will be automatically converted to 60 W, some laptops in the flight power mode will stop the power supply reception of the external adapter. This feature is enabled for machine hardware configuration/power consumption, BIOS/EC/FW, and power management
