- Q: What is the relationship between the output voltage of the switching power supply and the PWM signal?
- Brother ~ ~ give you advice ~ ~ power problem is not so good ~ ~ ~ Switching power supply output voltage is controlled by the PWM duty cycle to achieve the adjustment ~ When the pulse width, duty cycle increases, the output voltage increases, otherwise ~ ~
- Q: What is a linear adapter and a switching power adapter
- Ordinary through the frequency transformer re-finishing filter series adjustment regulator (such as integrated chip 78XX) is a linear adapter; use of switching power supply called switching power adapter.
- Q: What is the basic principle of switching power supply?
- So as to achieve automatic adjustment of the high-frequency pulse voltage duty cycle to achieve the final output DC voltage stability. Adjust the output DC voltage principle is the same, with artificial methods to change the oscillation frequency and pulse duty to achieve the purpose of changing the output DC voltage. Simply put the basic principle of switching power supply is: AC variable DC variable pulse voltage and then change the process of a DC. It has a high precision regulator, small consumption and other characteristics.
- Q: Working principle of small switching power supply
- Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for transformer, resulting in the required group or groups of voltages! The reason for the high frequency AC is that the high frequency AC is much more efficient than the 50HZ in the transformer transformer circuit. So the switch transformer can be done very small, and the work is not very hot! The The cost is very low. If not 50Hz into high-frequency switching power supply does not make sense
- Q: What are the main components of the switching power supply?
- This is just one of the program switching power supply as a whole is the filter rectification adjustment feedback control output rectifier filter several parts. Specific programs according to specific requirements
- 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.
- Q: What is the difference between a switching power supply and a switching regulator?
- 2, switching regulator, the key word is in the regulator, so the output of the switching power supply has a negative feedback sampling circuit, can play the role of regulation, usually switching power supply efficiency will be relatively high, the input dynamic range comparison Large, dynamic response is better, so now more widely used.
- Q: Why switching power supply with two series capacitor filter, with a can you
- The two capacitors are used in series because the circuit uses a symmetrical dual power supply, and the capacitive + - connecting pin is the common ground of the circuit. Computer power is such a circuit, you can see there are two 220v470u electrolytic capacitors. The use of symmetrical power supply is to reduce the use of the circuit voltage, improve circuit safety.
- Q: Computer host switch power supply how much money?
- This is cheaper, more than 20 dollars on the line
- Q: Such as my primary with double shares 0.51 line, the secondary with four shares 0.51 line, if the secondary I used two 0.71 lines to replace the four shares of 0.51 line influential?
- Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
