- Q: Today saw the day of the power principle, 220V mains --- primary and secondary EMI filter --- rectifier bridge --- high voltage filter (high voltage direct current) --- switch (high frequency pulse high voltage direct current) --- transformer (low voltage alternating current) --- Rectifier filter (low voltage DC output) But after I demolished a power supply, the high-voltage filter capacitor is followed by three switching transistor, then the transformer, then there are three switches and three tubes, and finally only the coil and capacitor circuit composed of the filter. The Expert help me explain how the process is achieved. The
- Alternating current. AC power through the transformer or AC, transformers and generators, like the use of the principle of electromagnetic induction to achieve the purpose of voltage conversion. But in life, the radio power output is DC, which is because after the transformer buck after the alternating current from the power supply in the rectifier circuit and filter circuit into DC. Generally between 3-9V. Alternating current (alternating ≈lt?r?ne?t) current [k?r?nt, k?r-]), referred to as AC. AC also known as "alternating current", referred to as "exchange". Generally refers to the size and direction of time with the periodic changes in the voltage or current. Its most basic form is sinusoidal current.
- Q: High power high frequency switching power supply with what rectifier
- Such as high-power charger on the use of this switch is suitable for high-power.
- Q: How to solve the switching power supply MOS tube and transformer temperature rise is too high
- For the secondary side of the transformer rectifier can choose more efficient synchronous rectification technology to reduce the loss. For high-frequency magnetic materials caused by the loss, to try to avoid skin effect, the effect of the skin effect, can be used to multi-stranded paint and around the way to solve. 5.2.2 switching power supply thermal design MOS tube conduction when there is a certain pressure drop, that is, the device has a certain loss, it will cause the chip temperature rise, but the device heat and heat capacity and heat dissipation conditions. As a result, the device power has a certain margin
- 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.
- Ordinary single-bit potentiometer If your switching power supply itself is with the regulator then the board should have a voltage regulator potentiometer that removed in a resistance and the same as the original can be a motor when the two can only use a block Fast on it
- Q: How to make the switching power supply does not delay power
- If you want to add their own words at the same time chanting Do not need to isolate the direct use of the input to control a switch when the input voltage is not the time to turn on the switch tube power output pull If you need isolation with optocoupler to control the switch tube
- Q: Why should go through the cross - straight - pay - straight conversion, rather than directly after the transformer buck after rectification, filtering, switching power supply is not a way to reduce costs? Parallel power supply is significantly better than switching power supply, why no one tried to do one?
- Switching power supply does not only play the role of power switch, but also can be set to sleep, the role of deep sleep
- Q: Explain several protection of switching power supply OCP; OLP; OVP; OTP; ESD; UVLO
- In order to switch the power supply stability and reliability, usually set many types of protection.
- Q: Switching power supply CE certification is probably how much money
- Or how much money, there are two or three thousand cheap, you have seven or eight points, of course, the requirements of high, then there are more than ten thousand, specifically look at your needs, look at my name in detail
- Q: Computer host switch power supply how much money?
- Switching power supply are generally in the chassis above the only bad repair
- Q: I do 12V2A switching power supply when the 2A load, under normal circumstances work is normal. But is the beginning of the load that moment, when adding more than 1.3A, the output voltage dropped first low and then quickly returned to normal, what reason? This is of course not normal, the same load, for someone else's power but not the problem. How should we solve this problem? Just test a phenomenon is that when the sudden removal of the load when the voltage is also the first drop and then return to normal state. How to solve it?
- this is normal phenomenon. The load becomes larger, to maintain the same voltage, the power output impedance will become smaller, power duty cycle to become larger, the adjustment is the time required, the dynamic response speed of the voltage drop will be relatively small.
We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
