- 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
- After the transformer is not a switch transistor, although the shape like, but in fact is the rectifier diode. Switching power supply process you are very right ah
- Q: Wireless communication room in the combination of switching power supply and integrated switching power supply and the difference between the respective functions?
- The central room of the DC power supply system is composed of AC power distribution screen, DC power distribution screen, switching power supply rack (including a control module and multiple rectifier module), two large-capacity battery and connect them between the power cable The The battery is a group of 24 components, each 2V. The total voltage is 48V. ? Wireless communication room in the general use of wall-mounted AC distribution box instead of AC power distribution screen, the use of combined switching power supply to replace the DC distribution panel and switching power supply (including control module and rectifier module), so called the combination of switching power supply, DC power distribution panel and switching power supply rack together. Plus two sets of batteries. The battery is a group of 24 components, each 2V. The total voltage is 48V. ? Integrated switching power supply is the AC power distribution and battery pack is also integrated into the rack, the equivalent of a rack to complete the central room of the DC power system all the features, but the capacity to be much smaller. Its battery pack is generally used 4, each 12V, the total voltage of 48V. I found on the Internet under the MCS3000D-3 * 50A power supply, should be a combination of switching power supply.
- Q: Switching power supply 220 / 24V input break can be frequent power off
- In fact, the general power is not particularly large switching power supply by the transformer independent of a group of windings for the chip power supply, so the power to start the power supply, so that the power is turned on and then plugged into the plug When only a large resistor can be used directly to start the chip, to be stable output, so there will be a little start-up time
- Q: Explain several protection of switching power supply OCP; OLP; OVP; OTP; ESD; UVLO
- ESD protection, ie electrostatic discharge, to avoid damage to the chip or electronic components due to static electricity; and low voltage shutdown (UVLO), undervoltage lockout, limiting minimum input voltage.
- Q: I made a switching power supply, using boost dc-dc transform, input 18V, output 30-36V variable. Found that the output voltage has 300mv ripple and 1V burr. Has been added 10mh inductance and 6600uf capacitor filter. Switch tube plus RCD buffer Output with choke and EMI filter,
- If you are measuring the ground wire, 1V thorn is not large, but you must take it out of the case, you can consider two ways 1, electrolytic capacitors and more can not solve the high-frequency noise, but with ceramic capacitors such as 10uF / 50V several and in the output port, the effect will be very good. 2, in the output plus a common mode, high frequency. You can reduce noise. The above two methods are feasible, you try it yourself
- Q: Car cd with the battery all right, with a switching power supply speaker has a buzzing sound
- Recommended frequency transformer. Switching power supply is prone to interference, not easy to handle
- Q: Switching power supply OLP and OCP these two are the same concept?
- OLP is overload protection, to prevent the main power lines due to overload caused by overheating protection and installation of overload protection equipment.
- Q: What is switching converter and switching power supply?
- Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. Switching power and linear power compared to the cost of both the output power increases with the growth, but the growth rate of the two different. Linear power costs at an output power point, but higher than the switching power supply, which is called the cost of reversal point.
- Q: Switching power supply, Fairchild Semiconductor's switching power supply chip data, the application of the chip design switching power supply can be divided into two categories: Adapter and Open Frame, and the general application of the former Adapter mode design power than the latter will be large The What kind of structure or type, what is the difference between the two?
- Adapter has a closed shell, openframe no shell, the former heat dissipation is relatively poor.
- Q: Such as my primary with double shares 0.51 line, the secondary with four shares 0.51 line, if the secondary I used two 0.71 lines to replace the four shares of 0.51 line influential?
- Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
