-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 t

cycle of the switching power supply, t is equal to 2 times the switching time ton; Delta up-P is the ripple voltage of the output voltage, ripple Voltage Delta up-P is generally used to take the peak-peak value, so the ripple voltage is equal to the voltage increment when the capacitor is charged or discharged, that is, Delta up-P = 2 △uc.Similarly, the calculation results of the (1-90) and (1-91)

instability, causing the problem of power integrity, so one of our design purposes is to minimize the above two types of voltage, there are two ways: Minimizing the rate of change in the loop current: This means reducing the mutation speed of the load-absorbing current, limiting the number of power ports that share the

greater the better. Fifth step. The fault in the ATX power supply that I have repaired is generally the failure to respond to pins 14 and 15.50% of the fault is no +5v standby voltage, as long as the standby power of the switch to the +310v between the base to the start of the resistance to replace can be repaired, the resistance is generally around 500k-600k,

kHz (hard switch) and 300 kHz (soft switch ). The Technical Progress of IGBT is actually a compromise between the on-demand voltage drop, fast switch and high voltage capacity. Along with the technological and structural forms, IGBT has been developing in the history of 20 years. It has the following types: pass-through (PT) type, non-pass-through (treaty) type, and SPT type) type, groove type, and electric field cutoff (FS) type. Silicon carbide SiC

The power distribution system should meet the requirements of the Information Equipment Room, ensure the reliability and flexibility of power supply, ensure personal safety, facilitate construction, maintenance and management, and achieve advanced technology, economic and reasonable. The lighting system complies with relevant national regulations. More integrated

characteristics of high voltage regulation precision, no use of power transformers, etc, it is an ideal regulated power supply. Because of this, switching type regulated power supply has been widely used in a variety of electronic equipment, this paper describes the working

Detailed description of data center Power Supply Mode Electricity for data center equipment, just like gasoline for cars, cars cannot start without oil, and data centers cannot run without electricity, therefore, electricity is the most important thing for Data Center devices. All those who have learned the power base know that electricity is mainly divided into

distribution screens. The solution features: (1) considering the cost of system implementation, the data center load is divided into two types: single power supply/three power supply load and double power

body is touched, it may generate electric sensing. Co-state throttling (Ac-connected inductor) In the filter circuit, the common mode Throttling is connected in series on the FireWire (L) and Neutral Line (n) to eliminate online low-pass common state and RF noise of power supply. Some power supply input lines will b

. Therefore, some important departments and systems in the project must consider uninterruptible power supply UPS. AC uninterruptible power supply system Power

concerned, the power supply stability of the bridge rectifier. Third, the power supply fan In the process of power supply, the fan plays an important role in the configuration of heat dissipation. Disperses the piece only to ci

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

the filter capacitance in the linear regulated power supply. The circuit form is flexible and diverse. 　　For example, there are self-excited and he-type, have wide-width and FM type, there are single-ended and double-ended, etc., designers can play a variety of types of circuit features, design to meet the different applications of switching voltage regulator
