Q: What is the working principle of the power switch?: But we also note that 300V DC power added to the standby power switch and standby power switch transformer, the standby power switch is designed to self-excited oscillation mode, standby power switch immediately start working in the standby power switch transformer times Level output two sets of AC voltage, the rectifier filter, the output + 5VSB and +22 V voltage, +22 V voltage is designed for power supply internal control IC power supply. + 5VSB voltage for the standby voltage, the output to the motherboard. When the user presses the power button of the chassis, the motherboard sends a power-on signal to the power supply. At this time, the (green) color line is low, the IC's internal oscillation circuit starts immediately, generates the pulse signal, The signal is applied to the base of the main switch tube by pushing the transformer so that the main switch is operated in the high frequency switching state. The main switch transformer output voltage of each group, after rectification, filtering and regulation, get each group of DC voltage, the output to the computer host. But the CPU on the motherboard at this time has not yet started, must wait + 5V voltage from zero to 95%, IC detection +5 V rose to 4.75V, IC issued P.G signal, the CPU starts, the computer work properly. When the user shuts down, the green line is at a high level, the IC immediately stops oscillating, the main switch tube because there is no pulse signal and stop working. -12 to +3.3 of the voltage drop to zero. The power supply is in standby mode. Protection circuit principle brief: In the normal use of the process, when the IC detects the load is in: short circuit, overcurrent, overvoltage, undervoltage, overload and other state, IC internal signal, so that the internal oscillation stopped, the main switch tube because there is no pulse and stop working The So as to achieve the purpose of protecting the power supply.

Q: Switching power supply and communication power difference: Switching power supply is a high-frequency oscillating electronic circuit for voltage conversion. The main contents are: step-up or buck, direct current conversion to alternating current, or alternating current to direct current.

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: Why some switch power there are two switch tube? Two transformers, one big and one small series: There are four have not seen a transformer to promote a transformer on the main transformer, two tubes, but not push-pull or half bridge

Q: "First AC into DC, and then into a higher frequency of alternating current through the high-frequency transformer voltage conversion" Why? "LED display as a high-precision instrument to select the switching power supply instead of the transformer" Why?: Switching power supply and the difference between the transformer is a very stable switching power to a certain range of voltage into a very low voltage or high voltage (such as 110V-250 input, the output voltage can be stable control in the required voltage plus or minus 0.5 V)! Transformer output voltage is changing with the input voltage, that is, the input voltage increases the output voltage is also increased, the input voltage to reduce the output voltage is also reduced. Because the switching power supply is the first AC into DC, DC power through the power switch and then become a higher frequency of alternating current through the high-frequency transformer voltage conversion is not only efficient and high frequency after the greatly reduced the volume, but also save the copper and iron loss. Because the switch is controlled by the power switch, the switch is turned on for a short time and the output voltage can be maintained. When the load is large, the switch keeps working to keep the output voltage. So the switching power supply output voltage is stable, can be used as LED display and other high-precision instrument selection.

Q: In the design of switching power supply, the input power is smaller, switching transformer primary side of the inductance but the greater the? Transformer primary side of the greater the amount of inductance, the transformer is not the volume will increase?: (1) Low power is corresponding to large inductance Lp is inversely proportional to Ippk Lp = Vin (min) * Dmax / Ippk * f * k (Ippk: primary peak current K: current ripple rate) Ippk is proportional to the input power Ippk = 2Pin / (1 + k) Vin (min) * Dmax ∴Lp is inversely proportional to Pin (2) inductance volume and energy, and the relationship between the inductance is not absolute, large power is to correspond to the large volume of the inductor. In the case of a selected core L = AL * N? (AL: inductance (material dependent) N: number of turns) ∴ sense and the core material and the number of turns

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?: Shenzhen Luyuan Rui Di Electronic Technology Co., Ltd. is a professional design, development, production and sales of switching power supply professional company, the product has a low price, high reliability, high efficiency, low operating temperature Small size, light weight, etc., widely used in industrial control preparation, LED display, instrumentation and other industries, is the traditional control transformer ideal replacement products.

Stable performance, safe and reliable operation, the majority of users by the trust and respected, the best-selling products in major provinces and cities and overseas markets.

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: TOP and VIPER than: really TOP than VIPER price of your point, but the high frequency of 40K it, in fact, TOP223 can replace the VIPER, you do 20W output looks like TOP223 is not enough because the 223 wide range of input 85-265AC can only do 15W (P or G package), Y package 223Y can do 30W, but have to leave the margin? And 3844 compared to the first two: you can freely choose the appropriate MOS tube, higher operating frequency, a variety of forms of protection. The above is a more obvious difference, the specific or look at the cost of indicators required. You do not know how to use the multi-channel regulator with three? Cross adjustment rate has been a tune! Haha

Q: What is off-line switching power supply: You can not take the power, with their own battery switching power supply

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?: To increase the dynamic dynamic response speed of the power supply, it is necessary to increase the power supply bandwidth. With external feedback can adjust the feedback power supply bandwidth (bandwidth is easy to instability, to ensure stable power), or increase the output capacitor can also increase the power supply bandwidth.

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.
