- Q:What is the PWM high-frequency switching power supply
- PWM is pulse width modulation
As mentioned above, through the high-frequency switch output a pulsating DC, the filter output stable DC
If the load changes will lead to changes in the output voltage then the system will adjust the output pulsating DC duty cycle to achieve the purpose of regulation.
Upstairs that is the working principle of PWM-type inverter. What I'm talking about is switching power supply. Is actually a principle.
- Q:Your company's switching power supply through what channels to purchase?
- Mainly to see the demand, and then consider the price. A good power supply in the range, polarity, response speed, input control and other aspects of the characteristics
- Q:Ask a question about switching power supply
- DC power supply inside the capacitor caused by leakage can not bring the load, I have previously repair, replace the filter capacitor to solve the problem. Leakage, can only replace, you add more capacitors is useless.
- 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 industrial switching power supply
- Switching power supply is divided into civilian-grade industrial grade military grade of course different levels of power, safety requirements, performance requirements, insulation level and so on are not the same requirements, the same level of power also look at what work environment, require different power level The standard is different. Need power to find me
- Q:Who can help me choose a switch power supply model 220V AC / 10V DC
- This type of power Taobao is more than, as long as the input (power 10V DC) can be.
- Q:Switching power supply
- Switching power supply is usually divided into AC / DC, DC / DC, DC / AC and other types. Popular is to convert a voltage into a specific voltage for the needs of electrical equipment. Such as car switching power supply is the car's 12V DC voltage into 5V or other voltage for the use of equipment.
Commonly used mobile phone charger (also switching power supply), computer power and so are switching power supply.
- Q:Monitor switching power supply is not a problem?
- Power supply is insufficient, four of the best choice of five or more switching power supply!
- Q:How to make the switching power supply does not delay power
- The relay directly to the circuit off, the big capacitor may be continued to flow about
- Q:How to adjust the input voltage range of the flyback switching power supply
- How do not provide transformer parameters?
The maximum power of your power is 1.25W, the overall power supply power by 70% efficiency of 1.8W.
In this case need to modify the transformer. To the place there are the following:
1, the transformer to increase the ratio; such as the original is 200: 5, now changed to 300: 5. Now want to do your request 60-80VAC input protection, you need the current transformer parameters to be calculated;
2, the transformer sensation increased; proposed to change to 4mH ~ 8mH.
Once the two done, the protection voltage will rise.
I am an electronic design engineer, is developing a 12V20A repair charger, you can add to my discussion.
Nowadays, our products are exported to numerous countres, like US, Australia, UK, etc. Successful improvements on technical processes and professional customer services have been recognized by more and more new or old customers. We hardly receive any negative feedback from customers. Our products so far have catched up with the consistency with world standard .
