- Q:Why is the DC regulated power supply connected to the load circuit after the voltage is reduced
- 1, the access load exceeds the actual power supply capacity of the power supply;
2, the power supply design problems: drive the drive force is insufficient, the base injection current is too small, the capacitor capacity is too small, etc.:
3, circuit parts have problems, resistance deterioration, transistor aging, etc.:
4, the AC power supply voltage is too low, AC low voltage side voltage is lower than the required voltage, etc.:
5, the transformer power is too low - inadequate.
- Q:Is the switching power supply output from a regulated or pulsed power supply?
- This is hard to say, switching power supply is very wide, can be DC power (regulator or steady flow) and pulse power, depending on the specific load demand.
Better mobile phone charger is the output of the pulse, which is conducive to the battery life, the output of the DC also. On the phone battery charging is still more complex, not the general regulator or steady flow power can be completed, to use a dedicated chip. Regulator and steady flow operation should also be changed according to the charging process.
Please refer to the relevant literature.

- 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
- So the efficiency is very high. Through the switch transformer can output a variety of voltage.
- Q:Use multimeter and DC power supply should pay attention to what matters
- Multimeter use time to pay attention to gear.
Used to detect the circuit is good or bad when using low blocking.
- Q:Mobile phone charger can be DC power supply?
- 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:What is the working principle of an adjustable DC regulated power supply?
- Rectifier and filter circuit works, characteristics and calculation of the main parameters.
1 silicon voltage regulator diode regulator circuit
1 Zener diode characteristics
The use of silicon diode reverse breakdown characteristics, can produce a zener diode. The general diode is not allowed to work in the reverse breakdown area, because the reverse current IR is large, the breakdown power consumption P = IR ?? UBR is very large, beyond the maximum allowable diode power loss, the diode Will be burned. Zener diode junction area of the larger, allowing greater power consumption, as long as the breakdown power consumption does not exceed the allowable value, the Zener diode will not burn. For example, there is a Zener diode power consumption PZ = 500mW, reverse breakdown voltage UBR = UZ = 10V, then the maximum reverse current
- Q:What is the solution for a regulated power supply?
- AC power supply voltage fluctuations in the main situation of the following two points:
(1), the voltage fluctuated, can not be stabilized within the scope of the standard voltage permit;
(2), the voltage continues to be high or low. The above two cases for the safety of electricity and electrical safety are a lot of unfavorable factors. With long-term work in such a voltage environment will cause air consumption increases, increased current consumption, reactive power is high, a serious rise in temperature, electrical appliances can not work properly and so on. More serious will burn the electrical, and even cause a fire!
- Q:Adjustable DC regulated power supply can charge the car battery?
- There are many kinds of car level, usually as long as the maximum current charger does not exceed the battery charge current; the maximum voltage of the charger, not more than the battery voltage, can be charged.
But it is best not to use this, because the charger is usually constant voltage, constant current charge. In other words, the battery is not enough constant current charge, the battery is saturated when the constant voltage charging.
But if you can not find the right charger, the above adjustable power supply can be used as a charger, but pay attention to the charging current, otherwise the battery easily affect life.
- Q:DC power supply what brand of the better ah
- See you want to simulate or CNC.
And your budget, and the maximum voltage and current you want.
