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: 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: What is the working principle of the series DC regulated power supply protection circuit?: Second, the cut-off ????? The cut-off type can be improved on the above protection circuit. ????? In the protection of the base of the transistor preset a voltage, such as 0.5 volts, at this time, the protection transistor will be turned on. And then the voltage across the detection resistor is superimposed on the B pole, when the detection resistor detects a voltage higher than 0.2 volts, the two voltages are added, the transistor is fully turned on, the CE is short, the regulator is shorted and the output voltage is approximately 0 , Protection is complete. ???? The cut-off benefit is that you can use a smaller sense resistor to reduce the power loss on this resistor.

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: My graduation thesis needs, as long as 40 words is enough!: At the same time  communications, aerospace, military, automotive, computer, office and home appliances and other industries of the rapid development of the power system also put forward higher and higher requirements. The traditional power system due to performance constraints  to a certain extent, restricted the development of other industries.

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: Mobile phone charger principle (output mode): From the principle is possible, as long as the regulator DC power supply is a constant voltage source, and the output voltage is stable, there will be no voltage instability, such as voltage rise (voltage drop ignored), with a DC power supply to the phone Charging is no problem. As long as the regulator power output is stable enough, you can. Mobile phone charger is generally 5V, transferred to 5V, For lead-acid batteries, according to the single cell 2.3-2.5V voltage set the charging voltage, that is, 12V battery for the six single cell, the charging voltage is set to 13.8-15.0V, with constant pressure way to charge. Mobile phone charger can be divided into travel charger, seat charger and maintenance-type charger, the general user contact is the first two. And the market is selling most of the travel charger, travel charger in the form of a variety of common, cheap and cheap duck-type mini-travel charger, the general desktop card board charger, with LCD display of high-end desktop charge Device.

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: Why Capacitor Filtering in DC Regulated Power Supply: Large capacity capacitor or energy storage components! Can improve the power of the power load performance! The same can also short-circuit return residual high frequency And AC signal!

Q: Electrical Engineering! Why can not directly use a multimeter to measure the power supply of the exchange of ripple?: In general, multimeter AC can only measure the pure AC voltage. The output voltage of the regulated power supply is equivalent to the DC voltage + ripple voltage, and the multimeter exchange file can not be measured normally In addition, the ripple voltage is not necessarily a sine wave voltage, the regulated power supply itself or by external interference will produce complex ripple voltage, and the general multimeter AC voltage file is measured the average AC voltage. The ripple voltage is not a pure sine wave when the multimeter can not be accurately measured From the other side, the general linear power supply can only guarantee the output voltage in the lower frequency range of stability, and for more than tens of kHz ripple rejection is very limited. That is ripple voltage frequency is generally high, may have exceeded the multimeter AC file frequency response range, this time the multimeter is still unable to correctly measure
