Q:Maintenance of mobile phone power supply is best used to what
The use of transformer power supply, ripple is relatively small, ripple small noise, because the communication equipment, high noise requirements.
Q:DC power supply can directly charge the rechargeable battery?
Yes, but the effect is not good! Only one or two times, you can, a long time, the number of times, seriously affecting the battery performance. When used to adjust the adjustable voltage regulator output voltage. Can not be too high, otherwise there may be accidents, such as battery explosion, power damage and so on.
Q:Switching power supply with load capacity difference is what reason.
You are the design of their own power or repair products, has been successfully driven over the load did not. If it is repaired, he carefully check the circuit, replace the damaged original (such as the output of the filter electrolytic capacitor). If it is their own design. Please make sure you do the switch transformer there is no problem.
Q:From the old computer to remove a switch power supply can do what, can be used when the power? how to use?
Yes, mainly whether the power supply is sufficient. Voltage and current are appropriate. Use: find a green line of power output to the green line to the ground to switch power to work. Can also be connected to a switch to facilitate the switching power supply switch.
Q:What are the differences between linear regulated power supplies and switching power supplies?
Switching power supply is through the DC into a high-frequency pulse, and then the electromagnetic conversion to achieve voltage conversion and regulation.
Q:DC power supply, no load and load, the output voltage change it
Strictly said that certainly not the same. Even if the regulator itself has a dummy load, the output voltage will change when a new load is reached.
Q:I would like to ask: DC power supply when the ground terminal when used? how to use?
Ground (PE): not used for working circuits, only as a protection line. The use of the absolute zero voltage of the earth, when the equipment shell leakage, the current will quickly flow into the earth, even if the PE line has an open circuit, will also flow from the nearby ground into the earth   And then better, if it is a metal shell, to prevent electric shock; also can provide electrostatic discharge circuit   Connection: received three-core power supply on the ground, if there is buried copper pillars, then better in the above, because more pure
Q:DC power supply production
2, DC power supply welding According to the map to check, correct and then welding. In order to ensure reliable and does not damage the printed board, pay special attention to control the welding time to control the temperature of the soldering iron, to prevent Weld and copper foil stripping.
Q:LM317 to do 0-24V adjustable DC power supply 80
Use LM317 to do 0-24V adjustable DC power supply, more difficult to do a 1.25V-24V adjustable DC power supply, the circuit is very simple. This is because the LM317 adjustable three-terminal regulator, the minimum output voltage of 1.25V, if the required power supply from 0V from the tone, the regulator circuit need to add a negative voltage, power input on the need for positive and negative Three input, the relative circuit is more complex, the general power supply is no need to switch from 0V, so there is no need to join the negative power supply. LM317 output using 1.25V-24V circuit is very simple, direct soldering can be used, the two diodes in the figure to protect the three-terminal regulator with, can not increase.
Q:What is the solution for a regulated power supply?
In the input side of the regulator. At present, due to power supply facilities and regional conditions and other factors, China's AC power supply voltage fluctuations are still relatively large. Especially in some remote, rural areas.
