- Q: What is the component stress in the switching power supply?
- Component stress is the element in the worst working conditions of the environment, for component reliability, the actual consideration of the main voltage stress and thermal stress. General companies set their own derating standards, the use of components in the stress can not exceed the established standards in order to obtain improved reliability.
- 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
- General switching power supply under normal load voltage change ± 5/00 below, beyond the more, it is not normal. You should check whether the load is too large, the power capacity is sufficient, the power supply internal feedback loop is normal. 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, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply.
- Q: Switching power supply circuit will ring what will happen
- There are two cases of voltage regulator sampling circuit will cause the voltage rise but the design of a good circuit protection is perfect when the switching power supply will immediately protect and stop working there is a switching power supply on the sleek ring design of the voltage requirements are not very There is a strict need for power to have a faster response speed and large output current, such as some of the power amplifier is now open-loop design
- Q: Switching power supply where to buy? Is there a recommended shop?
- Hello, I am selling switch power, but do not know what kind of power you want, where people are. Please ask.
- Q: "First AC into DC, and then into a higher frequency of alternating current through the high-frequency transformer voltage conversion" Why? "LED display as a high-precision instrument to select the switching power supply instead of the transformer" Why?
- Electronic transformer "can be simply understood as" simple without switching power supply regulator " Mainly used for some need high-power transformers, and the frequency, output voltage and other parameters are not strictly required, but the cost requirements are very sensitive occasions, such as lighting applications in the spotlight transformer. Spotlights are purely resistive loads that are insensitive to operating frequency but require very high power. Therefore, the use of traditional power frequency transformers is costly and wasteful of copper and iron, so the most suitable use of "electronic transformers" to solve this need. "Switching power supply" PWM technology can control the output power to accurately adjust the output voltage, the input voltage changes can ensure that the output voltage unchanged, and "electronic transformer" does not have this function! "Switching power supply" has a lot of advantages compared to traditional linear power supply. High cost (efficiency, efficiency, load regulation rate) Therefore, the application field is very extensive, such as computer TV mobile phone charger used in PC power are "switching power supply" Electronic transformer and switching power supply working principle is almost; Are through the electronic components will be converted into low voltage piezoelectric; The difference is: electronic transformer is the high-voltage power frequency conversion into low-voltage high-frequency electricity, only need to transform the lighting applications; The switching power supply can output a stable DC voltage according to the design.
- Q: Switching power supply start-up time, hold time, long time, fall time, which standard
- Rise time: the output voltage from 10% to 90% of the time, the rise time is generally less than 50ms, too long may cause the machine malfunction. Hold time: After the input power is turned off, the output voltage is maintained with 90% of the specification time.
- Q: Electronic transformer, inductive transformers, switching power supply transformer What is the specific difference? What kind of situation which the election of a transformer? 5 Halogen spotlights require dimming control, LED lights have to dim, Will the high school electronic transformers, switching power supply can be used with dimming?
- Inductive transformer is the use of electromagnetic core by the primary / edge winding different turns to achieve the "transformer" purpose; electronic transformer and switching power supply transformer has a similar place, in fact, switching power supply is one of the electronic transformer. The method is composed of changes in the voltage generated by the circuit, the method is diverse, can be (frequency variable) AC output, it can be DC output. Switching power supply is the way of electronic switch, by the electronic circuit constitute the oscillator, through the high-frequency magnetic winding to produce different high-frequency AC voltage and then through the rectifier output different DC voltage
- Q: Output 12V2A switching power supply, I would like to change to 12V5A, is not the transformer changed on the line
- Of course, the first high-frequency transformer to be changed, high-voltage rectifier filter electrolytic capacitor to increase, U1 may be changed to mosfet, low-voltage output high-speed rectifier diodes and output electrolytic capacitors have to change, there are other ........ ....and many more! Change to do the test can be changed to use is not recommended to buy an ordinary 12v5A power supply should not be too expensive.
- Q: Switch power jumper do not know which one which then do?
- You say the switching power supply is the type of switching power supply,
- Q: Find the correct use of this constant voltage constant current switching power supply, and the current adjustment method
- Constant current switching power supply load regulation should be the same as the output current, the load (constant current type power supply is allowed to short circuit, short circuit output current should be its rated current) from the short circuit to the output voltage to the rated value , The percentage change in the output current. Usually the short circuit in the case of current will be too large, when the voltage close to the rated current when the current will be small. Only on behalf of personal views.
