- Q:2014 low-frequency transformer is now the future is ok, the feeling is now doing more switching power supply, the last low-frequency transformer will be replaced
- Not the same thing. Simply put, the transformer is a circuit of electronic components, and switching power supply is composed of a number of electronic components can achieve the corresponding power conversion circuit. That is, from the function: Different switching power supply can be a variety of different forms of electricity into another form of electricity, such as: Can complete the AC and DC high / low voltage conversion; can complete the AC high / low frequency conversion; can complete the AC / DC conversion and so on. (Switching power supply which can use the transformer as a circuit component) And if only a well-designed transformer as an electronic component, it can only achieve a fixed frequency AC high / low voltage conversion.
- Q:The hands of a switching power supply, the use of 2SC3320 switch, the output is 24V7A, after adding the load will always burn 2SC3320 switch, no load no problem, how is it, there are drawings, that expert help to see, thank you
- ? 7. Switch tube emission limit current resistance is too small ?????? 8. The switching voltage is damaged ?????? 9. Damage to the rectifier bridge ?????? 10. The insulation between the switch and the heat sink is poor ?????? 11. Switch tube performance or power is too small ?????? 12. B + rectifier diode is damaged ?????? 13. The input AC voltage is too high or too low Key Positive feedback is too strong to detect C10A, C10B, R14, R101
- Q:Switching power supply where to buy? Is there a recommended shop?
- Hello, I am selling switch power, but do not know what kind of power you want, where people are. Please ask.
- Q:What is the core of switching power supply design?
- The design core is of course switch and switch transformers
- Q:How to make the switching power supply does not delay power
- Use a relay to control the output of the switching power supply.
- Q:Would like to ask the switch power supply in the end is what role?
- Switching power supply is the principle of alternating current frequency into DC, and then convert DC into high frequency AC, through the switching transformer, feedback regulator and other processes into the voltage you need, through rectification, filtering, and then converted into DC The process, and MOSFET throughout the process through its continuous opening and closing, so that high-voltage DC into high-frequency AC process.
- Q:Switching power supply start-up time, hold time, long time, fall time, which standard
- Start time: that is, since the input power input to the output voltage reaches 90% of the specification time, from the boot to the machine to work time.
- Q:Switching power supply how maintenance
- Check whether the input, and then check the switch control circuit part, and finally the power drive sector.
- Q:Switching power supply maintenance methods can be divided into several steps
- 4, in the switching power supply repair practice, there are many switching power supply using UC38 × × series 8 feet PWM components, most of the power can not work because the power supply is damaged, or chip performance degradation. Starting current increases due to start circuit as shown below. When there is no VC after the open circuit, PWM components can not work, need to replace the same power resistance with the original resistance. When the PWM component starts to increase the current, you can reduce the R value to the PWM component can work properly. In the repair of a GE DR power supply, the PWM module for the UC3843, detection found no other anomalies, R (220K) and then a 220K resistor, PWM components work, the output voltage is normal. Sometimes due to the external circuit failure, resulting in the VR terminal 5V voltage is 0V, PWM components do not work, in the repair Kodak 8900 camera power supply, encountered this situation, connected with the VR side of the external circuit, VR from 0V to 5V, PWM components work properly, the output voltage is normal.
- Q:I have a 12V3A switching power supply. From 0V to 12V, 2V3V can start. Want to carry out voltage regulation. How to do? If you use the potentiometer to connect the kind of potentiometer. I connected to the permanent magnet three brush motor is the car with the wiper motor, the motor high and low speed adjustment. Originally wiper motor there are two blocks. Richer speed adjustment.
- With a potentiometer to the 12V3 amp DC motor speed, the voltage drop in the potentiometer (variable resistor) on the energy consumption of large (and fever), you that 12V3A switching power supply from 0V, 2V, 3V - -12V continuous adjustment
