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: Adjustable DC regulated power supply works: The working principle, application and prospect of the voltage source. First, the working principle of DC power supply DC power supply is a 220V frequency AC power conversion voltage regulator output voltage of the device, it needs to go through the transformer, rectifier, filter, regulator four links to complete. The working principle of the four links is as follows: (1) Power transformer: is a step-down transformer, it will convert 220V AC voltage to meet the required AC voltage, and sent to the rectifier circuit, the transformer by the secondary side of the transformer voltage The (2) rectifier filter circuit: rectifier circuit converts the AC voltage Ui into pulsating DC voltage. And then filter the filter circuit to filter out the larger ripple components, the output ripple smaller DC voltage U1. Commonly used rectifier filter circuit with full-wave rectifier filter, bridge rectifier filter.

Q: DC power supply is linear or switch: DC power supply with a linear power supply, but also switching power supply.

Q: I have a computer power supply, how to use it to change the power of other electrical appliances? 12V.5V must be. It has a lot of lines above, what color represents what the meaning? And then why is I connected to the power after the basic line basically no voltage output? Is there a thread that controls the output of the power supply?: There is a control power to open the line: that is the root of the green is the switch line, you and any one of the short black on the line! The The 1, + 5V (red line): Convert a variety of logic circuits. 2, + 12V (yellow line): Drive the disk drive motor and all fans (Exception: Laptop fans use + 5V or + 3.3V). 3, + 3.3V (orange line): For the CPU, motherboard, PCI (Peripheral Component Interconnect external device interconnection) bus, I / O control circuit power supply. 4, + 5VSB (Stand By, purple line): Responsible for the start of the remote power (greater than 720mA, the motherboard starts as long as 0.01A).

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: The circuit teacher said the capacitor can not be 10uf, should not the same! Specifically did not say, ask the big god say, the specific capacitor should be how much ah! Check a lot, not found! Thank you!: 7815 left side of the capacitor with a larger, such as 100uF, the right side with 47uF, 78 series regulator output voltage can not be higher than the input, or may cause damage to the regulator, the use of input filter capacitor is greater than the output filter capacitor Can ensure that cut off S1, the input voltage is higher than the output. In general, the voltage regulator capacitor capacitor capacity is better, so that the filter effect is better.

Q: What is the role of power supply regulator?: Of course, is to play the role of regulation ah, that is, we usually use the electrical instability, fluctuating too much when the crash is easy, power supply is to play the role of not let him crash

Q: AC power supply and DC power supply difference: AC power supply and DC power supply difference is: AC power supply is stable AC power, DC power supply is stable DC

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?

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.
