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: 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: A DC / DC switching power supply input with UC3843 is a 24V power supply between two power supplies is up to 200M line now the situation is DC / DC power supply at no time when the load is measured at this time DC / DC power input It is actually less than 15V if the DC / DC power supply is loaded with about 10W and the 24V power supply output is adjusted to 27V or more when the DC / DC power supply is working In front of the wrong In the load when the 10W when the front power output is adjusted to 27V measured when the power input voltage is 14.5V or so when the no-load time is normal add another point With 10W when the front of the power output is adjusted to 27V below the two power between the current is significantly increased at this time into the DC / DC power supply voltage from 15V down to 6,7V looks more like the back of the power from Excited and DC / DC of this power supply in the 9V or so input conditions can work properly: The reason is obvious, one is the power cord is too long, the second is behind the power efficiency is too low, both at least one or both. According to what you said, "when the load with 10W, when the front power output is adjusted to 27V measured after the power input voltage is about 14.5V", we can see 200 meters on the cable voltage drop as much as 12.5V! At this time the output power of the front power supply should be about 1A (assuming the efficiency of the power supply is about 80%), the power line resistance is about 12.5Ω. Because the power required for the rear is constant, the current will be greater if the transmission voltage is reduced and the efficiency of the DC / DC power supply will be lower. This long-distance transmission power and low-voltage transmission is not appropriate, should be used AC / DC isolation module from 220V AC voltage conversion required power.

Q: I copied a circuit board, 7W switching power supply, line and the original circuit is exactly the same, that is slightly different alignment, no power after the output. I made two boards, are the same ask, ask the master, where is the problem? How to deal with?: IC is generally the auxiliary power supply is a problem, the relevant components to check: R8, R9, Q3, Z1, D5, R14, and transformers. Finally, U2. The main thing you want to look at the voltage of the IC VCC pin is not within its specified range, if the IC problem, if not, from the C1 positive step by step to find over.

Q: The original circuit is in accordance with the 20K switching frequency design inductance, and now the switching frequency to 10K, do not know if this will be any problem? Inductance in the output of relatively large power, there will be buzzing sound, what is the reason?: Generally do not put the frequency of work can be heard on the frequency, that interference will be very painful!

Q: Switching power supply TL431 what role, I did not find the circuit in 431 the corresponding circuit: Capacitor in the role of the circuit: with blocking DC, connected to the exchange, to prevent low-frequency characteristics,

Q: Switching power supply gnd is doing: Related to some: VDD: supply voltage (unipolar device); supply voltage (4000 series digital circuit); drain voltage (FET) VCC: supply voltage (bipolar device); supply voltage (74 series digital circuit); VSS: Ground or power supply negative VEE: Negative voltage supply; source of the FET (S) VPP: Program / erase voltage. GND is divided into digital ground (SGND) analog ground (AGND) ? The answer is recommended by the users

Q: Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.: Inductance: inductance, also known as self-inductance coefficient, is the inductance of the original sense of self-inductance of a physical quantity. When the magnetic flux through a coil changes, the coil will produce potential, which is the electromagnetic induction phenomenon. The resulting potential is called the induced electromotive force, the magnitude of the electromotive force is proportional to the velocity of the flux change and the number of turns of the coil. The basic unit of inductance is H (H), there are cents (mH), micro-Heng (uh). 1H = 10 ^ 3mH = 10 ^ 6uH The air gap is the gap between the motor stator and rotor. The stator does not turn, the rotor needs to turn, so the air gap is necessary, according to the different motor, air gap size is also different. In general, the asynchronous motor air gap is small, synchronous motor air gap. Energy storage mainly refers to the storage of electricity. Energy storage is a term in oil reservoirs that represent the ability of reservoirs to store oil and gas.

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 ~: IGBT tube is the most commonly used IRGP20B60PD. MOS tube is the most commonly used IRFP450, IRFP460. Transistor is the most commonly used 2SK2850.

Q: Will the switching power supply fake load how to calculate?: Switching power supply fake load, the main purpose is to overcome the no-load or light load output instability. And the output is unstable, the primary D is too small, the energy is not open is the secondary overshoot voltage or feedback current is too large, forced IC to reduce D;
