Q: DC power supply, no load and load, the output voltage change it: But in the request is not high, you can think that the two are the same, or how the function of the regulator it?

Q: What is the difference between regulated power supply and steady current power supply?: A steady voltage, a steady current. Stable voltage at rated power, the voltage is adjustable and can be fixed on a value. Does not change as the input changes.

Q: Half-bridge switching power supply and the commonly used by the three-terminal regulator block compared to the power supply, what are the characteristics: Three-terminal regulator block is a series of regulated power supply, regulator tube work in the amplification zone, the tube dissipation power, low efficiency.

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: DC power supply is linear or switch: Linear power supply external characteristics of excellent, and switching power supply itself is high efficiency, the load interference, each has its own advantages and disadvantages, according to the specific requirements of the power supply equipment selection.

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: DC power supply technical indicators which: 3, the limit index (1) the maximum input voltage Is to ensure that the DC power supply safe operation of the maximum input voltage. (2) the maximum output current Is to ensure that the safe operation of the regulator to allow the maximum output current.

Q: Switching power supply and ordinary power supply compared to what advantages: Advantages: (with power ratio between) small volume Power is large efficient flexible

Q: What should I pay attention to when using a function signal generator and a DC regulated power supply?: Use DC power supply should pay attention to the output voltage and current with a load and have a certain margin, wiring, attention to positive and negative polarity do not short circuit

Q: What is the current of the DC regulated power supply?: Under normal circumstances, low-voltage DC power supply current will change with the resistance changes. That is: the voltage must be, the current resistance with the resistance of the regular changes in the resistance. To adjust the current, the regulator circuit is generally designed to adjust the regulator circuit. Sometimes, DC power supply output unchanged, with electrical resistance is small, and do not want the resistance flow through a lot of current, I used three methods commonly used, one with thyristor to adjust the circuit, through the control of thyristor The current is generally suitable for the current requirements of the current is not high resistance circuit; the second is to use the transistor to adjust the circuit, by adjusting the transistor base current to adjust the current through the transistor ce set. 500mA below the small current with a class of C9013 C8050 can be a large current available 3DD102c like the tube, the maximum current 5A, can also use other transistors, according to the actual needs of choice. The third is to use adjustable voltage integrated circuits, such as LM2576-ADJ, LM317 and so on. In fact, by adjusting the voltage to adjust the current.
