Q:What is the regulated power supply?
Is a constant voltage power supply, can be AC, it can be DC, according to the needs of different voltage regulator is not the same.
Q:I have a 220v buck regulator output 12v power supply, how to calculate its output power? I measured with a digital multimeter output port voltage is 12v, and then transferred to the current block, directly to the meter measured power output port, did not show, is not the way to measure the current is not right? How to test specific Or there is no way to calculate the power of the power, I now know the voltage is 12v, but the current does not come out ah? Put away How do I know the power of my regulated power supply?
When measuring the current to the meter in series in the circuit, that is, first disconnect the circuit and then disconnect the meter at both ends.
Q:What is the DC power supply load characteristics of the curve, how to determine, good and bad What is the performance, if not good, how to improve it, please advise people
Of course, the DC power supply is the smaller the better resistance of Kazakhstan, that is, do not divide too much voltage, and if the current source, then the smaller the better resistance. In fact, the main thing is to see its stability is good. As for what is its load characteristics, I think it is different load, look at the load voltage is stable, of course, is probably the meaning and, I am not sure that you can control their own books, you know The
Q:Do you need to consider the power to choose a regulated power supply?
Be sure to consider the power, if the load required power is greater than the power supply, the power will be damaged. Power output power can be roughly estimated, the estimated method: the maximum output power of the power supply = output voltage x maximum output current Rated output power of the power supply = output voltage x rated output current
Q:It was strange to see a regulated power supply consisting of the op amp LM308A and the PNP transistor 2N2905. The output of the op amp does not return to the base of the transistor as usual, but returns directly to the inverting input of the op amp. The base of the transistor is connected to the positive voltage input of the op amp, connected by a resistor and the positive pole of the power supply. Do not know the working principle of the circuit, the role of the transistor, the output voltage regulator is how to adjust, do not know where the source of the circuit? I hope you experts advise!
I was the first time I saw this structure, I understand this: LM338 - 5.0 is a precision 5V voltage reference, the dynamic internal resistance is very low, the typical value is 0.6Ω, op amp LM308 is the emitter follower connection, 2,3,6 feet equal, that is, V2 = V3 = V6 = 5V, Rs and triodes constitute a parallel regulator circuit, and the op amp is the controller. Vin ↑, V3 ↑, V6 ↑, Io ↑ (op amp output current), I7 ↑ (op amp supply current), Ie ↑, URs ↑, Uout ↓.
Q:Maintenance of mobile phone power supply is best used to what
Switching power supply small and exquisite, but the ripple is relatively large.
Q:It is required to output 0-250V continuously adjustable AC voltage in the case of mains input fluctuation. The load is only one coil of 800 ohms, so the power consumption is very small. What are the recommended models? how's the price?
Variable frequency power supply is rectified filter, and then inverter, get adjustable voltage.
Q:Can DC power supply be used as a charger for lithium batteries?
Plus a current limiting resistor can be. Lithium battery to bring a protective plate, will automatically turn off after charging.
Q:Need a circuit, marked the size of the components, it is best to have a detailed calculation process. The circuit diagram can be viewed under MULTISIM Or send something to my mailbox Do good cash reward
LM317 voltage output range is 1.25V ~ 37V, 1.25V below can not guarantee. Circuit diagram is as follows, the voltage calculation formula Iadj is very small (50μA) can be ignored, the potentiometer resistance selection 4.7kΩ can meet the output voltage 1.25V ~ 24V adjustment range.
Q:Ac variable dc power supply with proteus can be achieved?
no need . Proteus only simulation, the software has a DC power supply, can be used directly.
