Q: What is the working principle of the series DC regulated power supply protection circuit?: Second, the cut-off ????? The cut-off type can be improved on the above protection circuit. ????? In the protection of the base of the transistor preset a voltage, such as 0.5 volts, at this time, the protection transistor will be turned on. And then the voltage across the detection resistor is superimposed on the B pole, when the detection resistor detects a voltage higher than 0.2 volts, the two voltages are added, the transistor is fully turned on, the CE is short, the regulator is shorted and the output voltage is approximately 0 , Protection is complete. ???? The cut-off benefit is that you can use a smaller sense resistor to reduce the power loss on this resistor.

Q: There are positive, GND and negative, GND and negative connected together.: If your power supply is the two output terminals, the negative side as a reference, you can think it is a positive power supply, with positive for reference, it can be considered a negative power supply.

Q: Why study DC power supply circuit: As for why the acceptance of DC power supply circuit, is certainly to do DC power supply.

Q: A customer's voltage has been unstable, often burned home appliances, light computer power to burn three, and everyone to give him a regulator is equipped with a voltage regulator or with a bad UPS, which is durable, thank you The There is probably the price is the computer and its surrounding equipment.: If the mains voltage is 175V-265V and the fluctuation is not very frequent, the on-line UPS (with regulator) can be used as a voltage regulator. The voltage is out of this range. The UPS is powered by the battery. The standard battery is powered continuously for about 10 minutes. 500VA400-800 yuan. If the voltage fluctuation is not, often power failure, or with the regulator effect is good, after all, is a special regulator (UPS is mainly used when power failure), failure rate .500VA precision purification power 400-700 yuan, do not change battery!

Q: Switching power supply and ordinary power supply compared to what advantages: Switching power supply efficiency is high, heat loss low!

Q: DC power supply which parts of the composition of the various parts of the role of what?: In addition, DC power supply is mainly composed of four parts: power transformers, rectifier circuit, filter circuit and voltage regulator circuit.

Q: In front of two, followed by two, are generally a relatively large and then a small tiles. What is the role? What is the difference between before and after? For example, 7805 this figure!: Large capacitor from the role of low-frequency filter, a small capacitor from the role of high-frequency filtering.

Q: How to choose a regulated power supply: First you use the power supply to determine the load, such as you want to access the load voltage is 12V, the load current is 4.3A, then you choose to power supply, we must choose 12V / 5A power supply.

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: Switch DC power supply is what it means: Switch is a diode circuit, the grid voltage when the corresponding diode will automatically shut down, the voltage is too low will open, of course, this also depends on a variety of other components of the auxiliary can be so controlled. Simple metaphor is that the toilet toilet water, when the light will automatically add water, when the time will automatically turn off the same.
