Q:Home voltage instability, is a good regulator, or with a stable power supply?
Only AC voltage regulator, if this is not, buy a UPS, open the computer when the inverter, do not open the time, the battery charge.
Q:Is there a difference between a regulated power supply and a power adapter?
The first is the role of voltage regulator voltage is the second transformer power supply equipment
Q:Why there will be 12v power supply what is the use
friend! Most of the electronic equipment is powered by low voltage!
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:Is the switching power supply and switching power supply the same?
The switching power supply output is regulated (stable, does not vary with the input voltage), and the switching power supply output is not necessarily regulated.
Q:What is a linear regulated power supply
Linear power supply adjustment tube work in the amplification state, and thus a large amount of heat, low efficiency (35%), need to add a large volume of heat sink, but also need to also large volume of power transformer, when the production of multiple sets of voltage output When the transformer will be more large. Switching power supply regulator tube in the saturation and cut-off state, and thus heat a small, high efficiency (75%) and save a large volume of the transformer. But the switching power supply output of the DC above will be superimposed on the larger ripple (50mV at 5V output typical), in the output and then connected to the Zener diode can be improved, and the other because the switch is to produce a large spike interference, but also need In the circuit, the magnetic beads are improved. Relatively speaking, the linear power supply is not the above defects, its ripple can be done very small (5mV below). For the power efficiency and installation volume requirements of the place with switching power supply is better for electromagnetic interference and power purity requirements of the place (such as capacitance leakage detection) multi-use linear power supply. In addition, when the circuit needs to be isolated when most of the current DC-DC to do the isolation part of the power supply (DC-DC from its working principle is the switching power supply). Also, the switching power supply used in the high-frequency transformer may be more trouble around the system.
Q:Use multimeter and DC power supply should pay attention to what matters
Multimeter is worth noting that the resistance file can not be no measurement voltage, pay attention to range. DC power output can not be short-circuited
Q:Adjustable DC regulated supply current is unstable
Your question did not make it clear that the load is the case of the current instability or how the matter. DC power supply is stable voltage, the current changes with the load changes, such as the load is the audio equipment, then the volume is large, the greater the current, so the current instability is normal.
Q:Maintenance of mobile phone power supply is best used to what
Switching power supply small and exquisite, but the ripple is relatively large.
Q:What is the solution for a regulated power supply?
In the input side of the regulator. At present, due to power supply facilities and regional conditions and other factors, China's AC power supply voltage fluctuations are still relatively large. Especially in some remote, rural areas.
