- Q:What is the PWM high-frequency switching power supply
- That is, the DC power to a high-frequency chopping to a pulse when the pulse is not broken when the wave will be able to get such a smooth waveform, such as sine wave Through the control of the pulse width in order to achieve the size of the output power control, such as sine wave peak width of the widest width and smaller pulse width when the narrow
- Q:Switching power supply isolated design, what is the meaning of isolation?
- Switching Power Supply The dual isolation design means that the transformers inside the power supply are electrically incompatible (they are magnetically coupled, the primary windings and the two secondary windings are not connected to each other), and the corresponding external and electrical paths are also Unrelated, both outputs are not common
- Q:What is the industrial switching power supply
- Switching power supply is divided into civilian-grade industrial grade military grade of course different levels of power, safety requirements, performance requirements, insulation level and so on are not the same requirements, the same level of power also look at what work environment, require different power level The standard is different. Need power to find me
- Q:Ming Wei switching power supply is why use?Ming Wei switch what to use, I see he is a circuit board, five wiring of the mouth, he used in the equipment what is the use? What is his general effect on the equipment?
- Regardless of the brand of switching power supply, the function is the same, to the equipment power supply, the general electrical equipment no matter what the external input is 110v or 2200v AC, the internal power are DC, usually with positive and negative 24v, 15v 5v And so on, switching power supply, is the exchange of alternating current into a stable DC for the use of equipment
- Q:What is the relationship between the output voltage of the switching power supply and the PWM signal?
- Hello, the output voltage of the switching power supply and the number of turns of the transformer, as you said the PWM is only control IC and MOSFET composition, PWM is "chopped" the input DC voltage cut into amplitude equal to the input voltage amplitude pulse Voltage to achieve. And the duty cycle of the pulse is regulated by the controller of the switching power supply. Once the input voltage is cut into an alternating square wave, its amplitude can be raised or lowered by the transformer. By increasing the number of secondary windings of the transformer, the number of output voltage groups can be increased. Finally, these AC waveforms are rectified and filtered to obtain the DC output voltage. Can be abstractly understood as the PWM is the middle process, as to the number of output voltage can be changed by the number of turns, of course, and efficiency is also related. Hope to help you!
- Q:Isolation switch power supply and non-isolated switching power supply advantages and disadvantages,
- Non-isolated type: Advantages: simple structure, small size, low cost; wide output voltage adjustment range Disadvantages: before and after the isolation, if the electricity supply, people touch the power output or the end of the ground may be risk of electric shock; only boost or buck or polarity conversion, the output voltage can not be equal to the input voltage. Scope: Input is within 36V low voltage (such as battery power supply); the entire circuit, including the ground can not be exposed to the occasion (such as dimming lamp)
- 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:Note the operating conditions of 220V voltage and the order of switching power supply
- 220v are low-voltage circuit, there is no provision, as long as the attention of several points: 1, do not touch the live part directly. 2, if you want to live work, you must ensure that the human body and the earth insulation (standing on the bench or insulation pad). Can not touch FireWire and Neutral Line at the same time. 3, the normal operation of the order: to use the switch off the circuit, first pull the sub-gate and then pull the total gate, the first joint gate and then sub-gate. Line maintenance sequence: Power off - pull the security ground - proof signs pull off the line - operation - review the operation is correct to complete the task - remove the insurance ground - remove the warning card pull off the line - power
- Q:New to buy the switching power supply, it should be bought fake, and after the output with the amount of output DC24V, then a small motor to 23.7, and a parallel down to 23.5, and on the 23V, and help me analyze Cause, change any solution
- This is normal. Switching power supply is also a power supply, there is resistance, the power output voltage can be expressed by the following formula: Uo = E-r × Io, where Uo is the output voltage, E is the electromotive force of the power supply, r is the internal resistance of the power supply, Io is the output current. R and Io of the product for the power consumption, do not work. E for a power supply, the basic is custom, equal to no-load voltage, also known as open circuit voltage. Through the formula can be tested, the output voltage of the power supply and output current is closely related to the larger output current, the lower the output voltage. The internal resistance of the power supply r is related to a variety of factors, including power tube, transformer, circuit, etc., different power voltage, the internal resistance r is very large difference is the main factor of power fever, r value is smaller, the higher the power efficiency , The more stable the output voltage. The use of smaller internal resistance transformer, power greater power tube, optimized circuit design can effectively reduce the power supply resistance.
- Q:Why some switch power there are two switch tube? Two transformers, one big and one small series
- There are four have not seen a transformer to promote a transformer on the main transformer, two tubes, but not push-pull or half bridge
