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?: First measure the current is required ammeter and load in series; Second, the different digital table may be different, and some digital table current block exclusive of an output plug, please note whether the right! Voltage is generally not measured, are almost the same as the nominal power = voltage in the X current, and the current and load, if it is no load when the current = 0, so to measure the current must be in the case of a load Measured out.

Q: How to control the DC regulated power supply output current constant? Such as constant output around 2a: 1, for the power supply, the output current depends entirely on the load, if the load is stable, the current is stable, if the load changes, the current must change. 2, if the load is constant, and the output current is greater than 2A, you can reduce the current through the series resistance, so that the current constant at around 2A. 3, if the load changes, want to get a stable current, should be used constant current source.

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: The working principle of DC regulated power supply: Figure 2 rectifier circuit Figure 3 shows the waveform In a bridge rectifier circuit, each diode is only conductive in half a cycle, so the average current flowing through each diode is equal to half the average of the output current. Each diode in the circuit receives the maximum reverse voltage (U2 is the transformer secondary voltage RMS). In the design, often use the voltage across the capacitor can not be mutated and the current flowing through the inductor can not be the characteristics of the capacitor and the load capacitor in parallel or capacitor and load resistor in series, in order to achieve the purpose of the output waveform is basically smooth. After selecting the capacitor filter circuit, the DC output voltage: Uo1 = (1.1 ~ 1.2) U2, DC output current: (I2 is the effective value of the secondary side of the transformer.), The regulator circuit can be integrated integrated three-terminal regulator circuit.

Q: My graduation thesis needs, as long as 40 words is enough!: Electronic devices are increasingly used in all aspects of social life, the vast majority of which need DC power supply to provide energy. In order to improve the performance of the power supply (such as reliability, safety, maintainability, high power density, high cost performance, environmental adaptability, etc.) and improve the electrical performance of the power supply (such as the source voltage characteristics , Efficiency, source effect, load effect, output voltage current ripple and noise, etc.), better for production, life service, more environmentally friendly, more energy efficient!

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: My home voltage instability in about 150 volts, what should be done to make the computer work properly, and do not hurt the computer? Installed power supply, or buy a regulator, or UPS installed. I heard that the regulator is not continuous power supply is not suitable for computer use! How can i do?: The regulator is the mains of the fluctuations to make it stable in the 220v, ups generally have this feature and when the power outage can also provide a few minutes to tens of minutes ranging from backup power, to the computer left to save and shut down time. No matter which of the two of your host power supply should be better quality, which will be directly related to the system is stable.

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: What is the main purpose of DC power supply?: General DC power supply for capacitors, relays, resistors and other components for sophisticated, test use, but also as a thermistor, motor and other electronic components experimental test use. With high accuracy, high accuracy, high stability and other excellent electronic properties.

Q: Ultra-low voltage automatic power supply how to use: Satisfied with the answer enthusiastic friends 2009-09-18 have wiring ah, then you can use the ah! Input to our socket power supply, output load. Very simple question: why use the voltage after the more unstable?
