Q:With a computer power supply how to make a separate power supply for other electrical appliances?
5, PS-ON (green line): Responsible for the operating system management power switch, is a motherboard signal, and + 5VSB together referred to as soft power. Less than 1V when the power is turned on, greater than 4.5V when the power off, the realization of software switching machine, the network remote wake-up function (set wake-up time, through the keyboard boot) (and GND then short-circuit can start the power supply) 6, -5V (white line): (Negative voltage rarely used, such as SFX removed -5V) 7, -12V (blue): PG signal (Power Good, gray line, + 5V signal (+ 3.0 ~ + 6.0V)): before the system starts, the power supply (0.1 seconds to 0.5 seconds after the power is turned on to issue the signal) for internal inspection and testing, To the motherboard a signal, so the power is controlled by the power supply on the motherboard monitoring components. PG signal is very important, even if the output is normal, if there is no PG signal, the motherboard still can not work; if the PG signal timing is not right, will open the machine.
Q:BEC (UBEC) and adjustable buck regulator power supply is different
The main heat from the regulator, the real control of the motor MOS switch in fact heat is not large) because of its efficiency is not high, the natural output current can not be large, the general maximum of 1A or so
Q:What is the working principle of the series DC regulated power supply protection circuit?
First, the current limit        In the circuit back in the middle of a small resistor, such as 1 ohm.        Connect the BE pole of the transistor 9014 at both ends of the resistor. The transistor of the C pole connected to the regulator at the Department. When the current is greater than the design value (such as 800MA), then the resistance at both ends of the detection voltage of 0.8 volts, higher than 0.7 volts, the protection transistor fully conductive, CE short-circuit, the voltage drop to the transistor saturation voltage drop, The At this point, the regulator is shorted and the output voltage drops to near 0 volts. Protection is successful.
Q:How to determine the power of the 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:Design DC power supply,
LM317 can output positive adjustable voltage LM337 can output negative adjustable voltage Both of these can meet your input voltage, output voltage range requirements.
Q:Use 7812 to make a positive 12V DC power supply
If the transformer secondary symmetrical center tap, with full-wave rectification, then the secondary voltage can also be set lower, 11.5V ~ 12V can be.
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:Ultra-low voltage automatic power supply how to use
` And then one is your regulator is broken! There is a load and you do not match the regulator, the regulator can not drag the load! Question: I was the regulator of the 3000V ``
Q:What is the meaning of the regulator accuracy?
The regulator is a device that stabilizes the output voltage. Regulator with constant voltage regulator, control circuit, and servo motor and other components. When the input voltage or load changes, the control circuit for sampling, comparison, amplification, and then drive the servo motor rotation, so that the regulator carbon brush position changes, by automatically adjust the coil turns ratio, thus maintaining the output voltage stability. Regulator accuracy refers to the output voltage fluctuation range is smaller, the higher the accuracy, such as electricity is very unstable, about what low, high precision regulator can be controlled within a safe range, like the computer this Precious equipment requires high precision.
Q:Transistor series regulator circuit
This is the standard series regulator circuit, but the transistor is not regulated, it is only used as a regulator tube, used to adjust the voltage. Circuit connected, A point voltage through the resistor R1 into the regulator D5, as long as the working range, the regulator will be stable at 21V; In fact, each regulator will have errors, the specific choice of the regulator can be found on its DATASHEET this error; Output to the voltage on the C3, that is, the voltage regulator tube to reduce the VT BE junction voltage (if it is silicon tube, is about 0.7V); Obviously, the difference between the input voltage at point A and the output voltage on C3 is added between the CE poles of the transistor. Whether the output current changes or input voltage changes, the regulator will be through the regulation of the transistor BE to complete the transistor CE to withstand the voltage to adjust to achieve the purpose of stabilizing the output voltage.
