Q:From the old computer to remove a switch power supply can do what, can be used when the power? how to use?
can! As long as the power is enough!
Q:DC power supply which parts of the composition of the various parts of the role of what?
Stabilized voltage supply is the English name of the power supply, which is a load device can provide a stable AC power supply or DC power supply of electronic devices, thus we know that the two major power supply voltage regulator is AC power supply with DC Power Supply. Among them, the DC power supply refers to the load device can provide a DC power supply of an electronic device.
Q:7815 power supply circuit diagram of the problem?
By experience, C1 and C2 can be larger, such as to take 1000 microfarads to 2200 microfarads, C3 smaller, you can go to 100 microfarads. Of course, the pressure is enough.
Q:What are the differences between linear regulated power supplies and switching power supplies?
Linear regulated power supply is directly connected in series with a controllable adjustment element to divide the input DC voltage to achieve voltage conversion and regulation, essentially equivalent to a variable resistor in series.
Q:What is the working principle of an adjustable DC regulated power supply?
AC power through the diode rectifier filter, after large, medium power transistor, large and medium power transistor through the resistance conduction output power supply. Some designs are connected in series with a resistor to supply voltage to the Zener diode, giving a stable voltage difference between the two poles of the diode, some of which are designed after the transistor output. This stable voltage is called the reference voltage. And then use a triode or manifold as a comparator, (+ output) one end of the reference voltage, the other end (b) a string of a current limiting resistor connected adjustable adjustable intermediate part of the adjustable resistance of the other two feet connected to the output voltage of the two poles The There is a pole connected, the power transistor triode, control the adjustment of the transistor conduction. Adjust the adjustable resistor to adjust the voltage. Simply put, the principle is the output voltage through the comparison tube (manifold) with the reference voltage comparison, to control the large and medium power transistor conduction current, voltage, to achieve the purpose of regulation. Adjust the comparison voltage of the comparative tube (manifold) to adjust the output voltage. Contempt ... ... sorry, for a long time do not touch, that large, medium-power transistor should be called what to forget ~ ~ ~
Q:Switching power supply and DC power supply difference
I think you should ask is the difference between switching power supply and linear DC power supply right? Switching power supply is the unstable DC power through PWM or other means into a series of pulses, and then these pulses to rectify and filter to get a stable DC power supply, this approach is relatively efficient. Linear power supply is through the way to get a stable power supply, low efficiency.
Q:High - precision 5V power supply
I have no way I used in the factory which are modular power supply can be used directly replace the need for easy maintenance If you like your power supply is damaged, then you have to go to the maintenance is the time to buy the general use of general power to use maintenance Time can be greatly improved As for the replacement of the power can be slowly repaired 12V output 5V power supply is generally not used 7805 you want to circuit with large capacity and chip peripherals but also simple it is impossible to drop, especially this DC to DC also It is very troublesome to turn back into exchange
Q:What is the working principle of the series DC regulated power supply protection circuit?
First, the current limit        In the circuit back in the middle of a small resistor, such as 1 ohm.        Connect the BE pole of the transistor 9014 at both ends of the resistor. The transistor of the C pole connected to the regulator at the Department. When the current is greater than the design value (such as 800MA), then the resistance at both ends of the detection voltage of 0.8 volts, higher than 0.7 volts, the protection transistor fully conductive, CE short-circuit, the voltage drop to the transistor saturation voltage drop, The At this point, the regulator is shorted and the output voltage drops to near 0 volts. Protection is successful.
Q:UPS is a regulated power supply, that UPM is what?
UPS is not a regulated power supply, is uninterruptible power supply.
Q:The difference between the series DC power supply and the parallel DC power supply
Ordinary series power supply are installed power transformer, with the output voltage stability, ripple, etc., but the voltage range is small, low efficiency. Parallel power supply output voltage is particularly stable, but the load capacity is poor, generally only in the instrument to do the benchmark with.
