- Q:Shell on the upper left corner and the lower right corner of the two screw holes. Why is the upper left corner screw hole designed to have only half a circular arc? Installed up the screw can only pressure a little bit edge. Fixed unreliable
- Side also has a fixed position to install, increase the installation of 90 ° bracket. L: then 220v AC line of fire N: then 220v AC zero line FG: then the earth G: DC output ground + 5v: output + 5V point of the port ADJ: is the output voltage within a certain range, the switching power supply output voltage is the original factory is fixed, that is, the nominal rated output voltage. Set this potentiometer allows users to the actual use of the situation in a smaller The output voltage is adjusted in the range. It is not necessary to adjust it in general.
- Q:What is the traditional way to convert alternating current to DC? What is the machine doing this function? Now with the general switching power supply What is the difference and what benefits compared to the traditional switch of this DC will be the machine?
- The traditional method is the low-frequency transformer buck, and then diode rectifier Switching power supplies are typically controlled by pulse width modulation (PWM) control ICs and MOSFETs The advantages are small, lightweight and efficient
- Q:AC-DC switching power supply, how to connect, input AC, AC, FG three ends
- Input AC, AC, respectively, then the power line FireWire, zero line, pay attention to view the two input terminals, preferably the power of the internal fuse connected to the other end of the line connected to the other end of the line, the fire line can also be connected to the normal line. FG ground wire.
- Q:Switching power supply how to connect to the battery charge
- The output of the switching power supply is connected to the positive pole of the battery, the output negative of the switching power supply is connected with the negative pole of the battery, and then the switching power input terminal can be inserted into the socket. If you do not know the battery and switching power supply positive and negative, you can use a multimeter to connect the switching power supply output port test, the display voltage is positive, then the red pen is connected to the positive, black pen is connected to the negative.
- Q:UPS and switching power supply what is the difference
- UPS is a power out, the computer can work for some time, the principle and the phone or laptop battery almost
- Q:Why the use of high-frequency switching power supply
- Improve the switching frequency can improve efficiency, thereby reducing the size of the transformer, and then the entire power supply volume will come down There is, switch state, oscillation, then the frequency of <20KHZ ears can hear the noise, so from this point of view can not be less than 20K
- Q:Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,
- This is a single-ended flyback switching power supply circuit, in this switching power supply, T2 is a high-frequency transformer, the role of voltage conversion, R11 is the starting resistance of U1, the input voltage of 85 - 2-265 AC, the choice should be in the 1--2W, 150 - 330K resistance between, usually need to use multiple resistors in series, otherwise it is easy to damage. R12 is the current limiting resistor of the switch, but also U1 overcurrent current detection resistor, the output short circuit when the voltage drop on the resistor will become high, U1 protection to stop the output drive signal. D6 is the transformer provided to the U1 supply voltage rectifier. C2 is the main filter capacitor, usually with electrolytic capacitors, voltage is greater than the maximum voltage input of 1/3, the capacity of about 1W / micro-law output. Q1 is the FET, is the switch tube. Generally also mos. D5 and R7, C5 are connected to the transformer primary to form the transformer spike voltage absorption circuit. When the switch is turned off, the moment the transformer will have a very high induced voltage generated, this circuit can be absorbed by this spike voltage (or is limited to a safe Of the range). Also called DRC or RCD spike voltage absorption circuit. U1 is the switch tube drive circuit, here should be a PWM integrated circuit, also known as pulse width modulation, is the English "Pulse Width Modulation" abbreviation, referred to as pulse width modulation. U6 is a photocoupler,
- Q:High power high frequency switching power supply with what rectifier
- Such as high-power charger on the use of this switch is suitable for high-power.
- Q:Working principle of small switching power supply
- Switching power supply works is: 1. AC power input rectified filter into a DC; 2. Through the high-frequency PWM (pulse width modulation) signal control switch, the DC added to the switch transformer primary; 3. Switching transformer secondary induction of high frequency voltage, the rectifier filter supply load; 4. The output part of the circuit through a certain feedback to the control circuit, control PWM duty cycle, in order to achieve the purpose of stable output. AC power input generally through the Euler circle of a class of things, filter out the interference on the grid, but also filter out the power of the power grid interference; In the same power, the higher the switching frequency, the smaller the size of the switching transformer, but the higher the requirements of the switch; The transformer transformer secondary can have multiple windings or a winding with multiple taps to get the desired output; Generally should also increase the number of protection circuits, such as no-load, short circuit protection, or may burn the switching power supply. Mainly for industrial and some household appliances, such as televisions, computers and so on.
- Q:Why switching power supply with two series capacitor filter, with a can you
- Two series to increase the pressure, improve the reliability of the power supply.
