- Q: How to check the switching power supply leakage current
- Need to use pressure tester. Through the pressure tester measured leakage current value, minus the switching power supply to the ground capacitance of the current value, is the switching power supply leakage current. Or disconnect the switching power supply to the ground capacitor, the voltage tester measured by the leakage current value is the need to measure the leakage current value.
- Q: What is the relationship between the output voltage of the switching power supply and the PWM signal?
- First of all, what is your circuit topology? Is BUCK, or isolated rebirth is it? Different circuits, the answer to your question is different. However, a large range can be explained as such. The larger the PWM duty cycle, the stronger the output load. (That is, the output voltage * the greater the output current.) You better, or look for the corresponding topology of your circuit information, find the formula, so good to understand some.
- Q: What is the flashing time in the switching power supply?
- Of course, there is no set of blanking time IC can be an RC filter to take this spike, the effect is the same.
- Q: 24-volt switching power supply why leakage
- 2, switching power supply high side and low side (that is, optocoupler across the 2 side, the general circuit board between the two sides will have a clear distance between the split) generally have an EMI capacitor (part of the power supply may also be connected in parallel with a high resistance )), Which is the reason why the switching power supply has leakage current.
- Q: 12V switching power supply, which brands through 3C certification?
- 3C certification is China's mandatory product certification, where the directory in the 3C certification required to be certified products need to be certified to the factory sales, import and use in business activities. The PC power supply belongs to the directory to be mandatory certification of products, so in the market of formal power products will be mandatory through the 3 C Such as HuntKey, Colorful, Great Wall, GOLDENFIELD, TT and Cool Cold's mainland sales products.
- Q: How to choose the switching power supply frequency?
- Have a few points! The size of the input voltage, the choice of transformer magnetic material, the choice of the main switch tube, there is the overall volume requirements can also be said to want to achieve the power density! For example: low-voltage input, such as 6-160VDC, when the pressure on the tube is not high, the switching loss is not dominant, the frequency can be relatively high,
- Q: Recently to be an automatic lift, switching power supply with the touch mode control and found that sometimes failure, into the frequency transformer is not the problem, the problem is only with the switching power supply, would like to ask if there is nothing to improve this Problem? Switching power supply is bought directly outside the back. There is not much change
- This is obviously the switching power supply caused by high-frequency radiation interference program crash. I've done it before. That is often said that the electromagnetic compatibility issues. Market switching power supply in order to save the cost of most do not do EMI treatment, so the interference is very serious. You can buy that kind of high-end switching power supply effect will be better. If their own solution, it may not be able to solve, but can proceed from below. Can be in the switching power supply line plus CLC filter, that is, plus X capacitor and Y capacitor and common mode inductance. You can also increase the filter capacitor at the output and add multi-level LC filter, note that L is the kind of core inductance. There is also a key thing to deal with is the high-frequency transformer, you can use copper waves to wrap it up, reduce radiation, increase the shielding layer. In addition can switch the power supply as a whole sealed in a metal box can also play a very good shielding effect, reduce the radiation on the surrounding industrial computer and chip interference.
- 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: AC-DC switching power supply, how to connect, input AC, AC, FG three ends
- If not marked L fire line, N zero line; AC AC can be connected to the fire line and the zero line;
- Q: Switching power supply, what is the hard switch? What is a soft switch?
- The so-called hard switch, power immediately after the output voltage, the soft switch is the voltage rise after the voltage rise output.
