- Q: What is the component stress in the switching power supply?
- Component stress, including voltage stress, current stress, temperature stress, power consumption
- 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: What is the basic principle of switching power supply?
- The basic principle of switching power supply is: The 220v 50HZ exchange, finishing 300v DC, the switch and the oscillation circuit, so that it becomes 40KHZ or higher frequency square wave voltage, coupled through the high-frequency transformer to the secondary, so that the secondary to get the required voltage The That is, the actual switching power supply, is the high-frequency transformer.
- 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 is the core of switching power supply design?
- There is no doubt that the transformer, PWM that a chip factory has been done, but turned into the most simple
- Q: Switching power supply, what is the difference between the charger
- 2, the switching power supply is a form of power conversion, the characteristics of the power supply is working in the switch state.As the switching power supply efficiency, so it has been a very wide range of applications. Charger is usually 220V AC power supply into the appropriate DC voltage, Charger can be used to make the charger, but he also used in color TV, VCD and other occasions, with one of the following one. The charger can be used to make the charger, but he also used in color TV, VCD and other occasions, with the following one Simple diagram to express the relationship between the two:
- Q: What is the difference between non-isolated flyback switching power supplies and isolated switched-mode power supplies.
- There is no transformer in the non-isolated circuit. The so-called forward and the flyback is very good, the flyback transformer has energy storage, transformer primary and secondary with the same name on the contrary, drive signal conduction, primary conduction, secondary cut-off, energy storage; drive signal cut-off, primary Cut off, secondary conduction, pass. While the forward transformer is no energy storage, and the primary and secondary are in phase
- Q: Output + 5V, plus or minus 15V, +24 V, not isolated 15V. Input 85 ~ 220AC, the total power of about 20 watts. I see three kinds of control chip, UC3844 similar products in the most widely used, but the internal non-integrated power tube, peripheral devices are more. VIPER I used the 12, the frequency fixed 60K, so the transformer will be relatively large, PCB also have to do big. I tend to use top223 similar products in almost no use top series, I worry about its stability, and the price of single tube seems to be the highest. These two days the boss will I set down, I hope a master to give pointers. If these three kinds of chips have any other differences also please enlighten, thank you
- No big difference, can be achieved, and the quality can also be designed to have no problem, in fact, you have to from the supply cycle, price and cost to consider, may wish to simply do the cost of three kinds of programs contrast
- Q: What is the impact of the refrigerator on the refrigerator?
- Incidentally tell you one, the refrigerator reaches the set temperature will automatically power off, there is no need for artificial switch machine. My home refrigerator has been running for more than five years, except for power outages, never stopped running, including winter.
- Q: Why should the switching power supply feedback the winding power supply?
- The chip needs a DC power supply to work. At the beginning of the boot, most of the power supply through a power resistor will be 300V DC high voltage step-down to provide to the chip. When the chip outputs multiple pulses, the feedback winding can provide normal power. Because in the normal work, the chip power consumption is also taught. Direct use of resistance buck, it is easy to lead to work instability. Therefore, it is the type of power supply feedback circuit to send the way to work.
