- Q: What is the flashing time in the switching power supply?
- Of course, there is no set of blanking time IC can be an RC filter to take this spike, the effect is the same.
- Q: What is the basic principle of switching power supply?
- The exchange through the diode rectifier. Capacitor filter into DC, and then through the 1620KHz high frequency oscillation generator. Switch and high frequency switching transformer role, the DC into the required amplitude of the high frequency pulse voltage. And finally through the high frequency of the two poles to the high frequency pulse voltage rectification. Capacitance filter output required DC voltage. The output regulator is to rely on the output to remove the sampling voltage to adjust the oscillator frequency and pulse duty cycle.
- Q: Hello everyone, I have a switching power supply chip with UC3845, fault: turn on the power instantaneous power indicator light and then off. After the investigation did not find a short circuit phenomenon. When the shortcomings of several consecutive shortcuts on the receiving side of the two pins, the power can be activated. What is the reason for this? thank you all!
- Oh, the above two answers I think can not help you solve the problem, because it is not feasible. First of all, according to what you say, you can accurately judge, you are full or overloaded when the normal start. This only shows a reason that the power is instantly activated when the impact is protected. The solution to the problem is to analyze the cause of the problem first. Where the protection is due to power on the moment when the load with the impact of over-current. So the overcurrent protection value should be slightly adjustable to solve. Such as single-ended flyback power supply, can reduce the resistance of the lower end of the MOS tube in order to increase the output over-current protection value, half-bridge or full-bridge circuit, then appropriate to reduce the peak current protection value or output over-current protection value, solved. Many of the output overcurrent or short circuit protection is used in the transformer primary side using the transformer (magnetic or magnetic core) to detect the transformer primary current, to protect the output overload situation. The value of this detected can be appropriately adjusted (the voltage drop resistance value can be appropriately reduced).
- 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: Explain several protection of switching power supply OCP; OLP; OVP; OTP; ESD; UVLO
- (OCP), limit the maximum output current; overload protection (OLP), limit the maximum output power; VDD overvoltage protection (OVP), limit the maximum input voltage; temperature protection (OTP), limit the maximum working temperature
- Q: What is the industrial switching power supply
- Industrial switching power supply refers to the switching power supply used in the industrial field Power can be divided into civil, industrial, military, and even aviation, aerospace Industrial switching power supply meets industrial requirements. For example, civil switching power supply generally require working temperature 0 ~ 70C, the industry is generally required in the -40 ~ 85C, military requirements are -55C can work properly.
- Q: I am in Guangzhou, need to purchase switching power supply, would like to know how we look for channels to buy? A lot of come to recommend the manufacturers, there are many outside the electronic market, there are a lot of online, I do not know how to distinguish between good and bad ah .... how to cost higher?
- Hello, now on the market power varies, the choice of power directly determines the product itself is good or bad, good power mainly to see the program, device platform, production technology, testing standards and a series.
- Q: Computer host switch power supply how much money?
- This is cheaper, more than 20 dollars on the line
- Q: For the specific parameters for the requirements (power: 350W or more working voltage: DC 300V) switch switch power supply which are commonly used? To say that there are specific places in Jinan where to sell? Anxious ~
- Are you going to IGBT tube? Can be commonly used are transistors and MOS tube.
- Q: Switching power supply, constant current power supply, resistance to the power supply where the benefits?
- Capacitive power supply is a constant current power supply, the principle of its buck is the principle of "series circuit resistance divider law", the advantage is very low cost, the circuit is very simple, high efficiency in the case of constant load. It is more shortcomings, the first is the power supply circuit and its output is not isolated from the output, followed by the value of the voltage divider and the load current, not suitable for large changes in the load of the circuit (changes in efficiency will be reduced), not afraid Short circuit but fear of open circuit, and the power supply may be an instantaneous surge current, the surge current will flow through the load, it must be protected. The power factor of the circuit itself is very low.
