- Q: How to solve the switching power supply MOS tube and transformer temperature rise is too high
- Switching power supply in the main components of the semiconductor switch tube, power diodes, high-frequency transformers, filter inductors and so on. Different devices have different methods of controlling calorific value. Power tube is a high-frequency switching power supply in one of the larger heat, reduce its heat, not only can improve the reliability of the power tube, and can improve the reliability of switching power supply, improve the average time between failures (MTBF)
- Q: Neighborhoods! Control transformer and switching power supply of the difference, for occasions, advantages and disadvantages
- Switching power supply is easy to damage because the switching power supply is a comprehensive manufacturing of electronic products, its overload capacity and over-current capacity are relatively poor, but the quality of the components, however, is easy to damage, like color TV switching power supply, but also multiple failures. Especially in industrial electrical equipment, because the equipment running a long time, the failure rate is relatively high. But the power grid voltage fluctuations are not, because the current switching power supply is mostly wide power supply design. The fluctuation of the grid voltage can only affect the output voltage of the control transformer.
- Q: Wireless communication room in the combination of switching power supply and integrated switching power supply and the difference between the respective functions?
- The central DC power supply system consists of two sets of switchboards, AC power distribution boards, DC power distribution panels, switching power supply racks (including control modules and rectifiers for rectifier modules), large capacity batteries, and connecting power cables between them. The battery is a group of 24, each 2V. The total voltage is 48V. Wireless communication room, the general use of wall-mounted AC distribution box AC power distribution screen, switching power supply to replace the DC distribution panel, switching power supply rack (including the combination of control modules, rectifier), the so-called portfolio switching power supply, Electric screen, switching power supply rack together. The other two sets of batteries. The battery is a group of 24, each 2V. The total voltage is 48V. Integrated switching power supply AC power distribution and battery pack integrated into the rack, the equivalent of a rack to complete the central room of the DC power system all the features, but the capacity is much smaller. Usually using 4 blocks, each 12V, the total voltage is 48V when it has a battery pack. I found online according to the Pacific MCS3000D-3 * 50A power supply, switching power supply combination.
- Q: I am now learning switching power supply, read some of the information in the "work in the CCM state of the flyback power", because of this do not understand, would like to ask the power of friends can give to explain, very grateful! As well as the principle of positive and reactive work mode? And tell me what I want to learn switching power supply only little knowledge of what I now learn from?
- he switching power supply's DCM and CCM refer to the type of power factor correction circuit (PFC). Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply. The switching power supply stabilizes the output voltage with the time ratio of the turn-on and turn-on of the switch, resulting in the way in which the energy is drawn from the grid is not carried out in a grid-powered manner (sine wave), which in turn affects the power factor of the grid and generates electromagnetic interference. So the switching power supply must have a power factor correction (PFC), if not up to standard product failure. The basic approach to correcting the power factor is to use inductors to gently ripple the energy from the grid, and the time ratio of the inductor to the turn-on and turn-off of the switch will in turn have an effect. In this case, how to achieve efficient output voltage (current) control is critical when performing power factor correction. DCM and CCM are two different control methods.
- Q: Teacher asked, I said that can improve power efficiency, there are small size and high efficiency characteristics. What else does it mean? For example, in the control of the characteristics of
- High-frequency switching power supply has many advantages: 1, small size, light weight. Vintage 100 to tile electrical appliances, only the power part of the large power transformer has a few pounds of heavy, accounting for a large position of the chassis. While the switching power supply only a few hundred grams, a small piece of palm. 2, saving materials. The switching power supply saves a lot of copper and iron. 3, stable and reliable. Switching power supply has multiple protection measures, the traditional power supply is the basic fuse. 4, a wide range of voltage adjustment, easy to achieve a wide range of voltage adjustment, the traditional power can not be compared. 5, switching power supply energy efficiency is high. 6, switching power supply to eliminate the traditional power of nuisance 50 weeks of communication sound. Switching power supply has so many advantages, has been more and more widely used to gradually replace the traditional power supply.
- Q: UPS and switching power supply what is the difference
- UPS is a power out, the computer can work for some time, the principle and the phone or laptop battery almost
- Q: I made a switching power supply, using boost dc-dc transform, input 18V, output 30-36V variable. Found that the output voltage has 300mv ripple and 1V burr. Has been added 10mh inductance and 6600uf capacitor filter. Switch tube plus RCD buffer Output with choke and EMI filter,
- Output in series with an inductor and then a capacitor in parallel LC filter circuit try to see if feasible?
- Q: What is the meaning of the magnetic ring color in the switching power supply?
- Magnetic ring color Magnetic ring are black A, Up to that is deep black, bright black this difference But the difference is not strict, Or button-type magnetic ring with a shell, sub-white black, gray We are doing this
- Q: Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.
- The same winding the same diameter of the conditions, the greater the air gap, the smaller the amount of inductance. The larger the air gap, the lower the permeability, the smaller the inductance.
- Q: Led lights switching power supply controller how to repair
- If you just use it alone, it's broken. It is recommended to buy one. Because the maintenance needs to change the device, and their purchase of equipment is expensive, and can not determine that the device is bad. If you are learning to repair, it depends on the principle of switching power supply. Principles of understanding, the manufacturers work, maintenance is very simple.
