Q: Is the switching power supply and switching power supply the same?: Exactly the same, there is regulation by regulating the pulse through the pulse width regulator.

Q: I have a 220v buck regulator output 12v power supply, how to calculate its output power? I measured with a digital multimeter output port voltage is 12v, and then transferred to the current block, directly to the meter measured power output port, did not show, is not the way to measure the current is not right? How to test specific Or there is no way to calculate the power of the power, I now know the voltage is 12v, but the current does not come out ah? Put away How do I know the power of my regulated power supply?: First, prepare a resistor (preferably the resistance wire, you can change the length of any), the resistance wire access circuit, measuring the no-load voltage and the ratio with the resistance wire voltage, constant adjustment of the length of the resistance wire, when the voltage is reduced by 10% , Measuring its current, this time is about the power of the full load power. Details can refer to the Chinese electronic DIY home of the relevant information

Q: DC power supply production: (3) lead wire shaping of electronic components When the electronic components are mounted on the circuit board, the pins of the components must be shaped in advance to accommodate the needs of the circuit installation. The lead forming of electronic components is mainly to make the installation of components to meet the size of the components on the printed circuit board mounting hole size requirements. (4) electronic components of the plug method ① the order of the pack: the first low after the high, the first small after the big first heavy light. ② identification of components: electronic components of the mark and color code should be up, in order to identify; horizontal plug-in numerical reading should be from left to right, and vertical plug-in numerical reading should be from the bottom up. ③ the spacing of components The distance between the components on the printed circuit board can not be less than 1mm; lead spacing is greater than 2mm. General components should be installed closely, so that components attached to the printed circuit board. Components meet the following circumstances should not be closely mounted, and need to float: A, axial lead need to be vertically inserted: the general components from the printed circuit board 3 ~ 7mm; B, large heat of the components (high power resistors, high power tube, etc.); C, heat after the performance of vulnerable devices (such as manifold blocks, etc.); ④ pay attention to the polarity of the diode, integrated circuit, electrolytic capacitor The circuit board due to fewer components, components of the installation order: diodes, resistors, potentiometers, electrolytic capacitors, electrolytic capacitors, integrated circuits in the order of installation. Before installation, pay attention to whether the component pin oxidation, the oxidation of serious components to be processed and tin.

Q: How to control the DC regulated power supply output current constant? Such as constant output around 2a: 1, for the power supply, the output current depends entirely on the load, if the load is stable, the current is stable, if the load changes, the current must change. 2, if the load is constant, and the output current is greater than 2A, you can reduce the current through the series resistance, so that the current constant at around 2A. 3, if the load changes, want to get a stable current, should be used constant current source.

Q: DC power supply is linear or switch: Linear power supply external characteristics of excellent, and switching power supply itself is high efficiency, the load interference, each has its own advantages and disadvantages, according to the specific requirements of the power supply equipment selection.

Q: My graduation thesis needs, as long as 40 words is enough!: At the same time  communications, aerospace, military, automotive, computer, office and home appliances and other industries of the rapid development of the power system also put forward higher and higher requirements. The traditional power system due to performance constraints  to a certain extent, restricted the development of other industries.

Q: Switching power supply and ordinary power supply compared to what advantages: In the past, we used most of the linear power supply, it brought a heavy transformer; Today, switching power supply, even the mobile phone charger are switching power supply. Advantages of switching power supply: 1. Small size, lighter weight (volume and weight only 20 to 30% of linear power supply); 2. Conversion efficiency is high, more power (switching power supply efficiency is generally higher than 70%, while the linear power supply only 30 ~ 40%); 3. Its own strong anti-interference, wide voltage range. Of course, compared with the linear power supply, switching power supply also has shortcomings, For example, the output ripple; due to switch mode work, there is a large electromagnetic interference.

Q: Why the output of DC power supply does not allow short circuit: The output short circuit will cause the output current greatly increased, so that the power supply itself is too large and burned, so the output does not allow short circuit. But this is not absolute, there is a perfect protection function of the transistor DC power supply, the output short circuit will not have any effect, but the short circuit, after all, is not a normal working condition. In fact, the resistance of the short circuit is very small, a small voltage will produce a lot of current, causing power or personal injury. However, most of the experimental power supply limited current, short circuit protection, short circuit will cut off the output.

Q: What is the solution for a regulated power supply?: AC power supply voltage fluctuations in the main situation of the following two points: (1), the voltage fluctuated, can not be stabilized within the scope of the standard voltage permit; (2), the voltage continues to be high or low. The above two cases for the safety of electricity and electrical safety are a lot of unfavorable factors. With long-term work in such a voltage environment will cause air consumption increases, increased current consumption, reactive power is high, a serious rise in temperature, electrical appliances can not work properly and so on. More serious will burn the electrical, and even cause a fire!

Q: What is the switching power supply?: A new type of power supply designed by the semiconductor device to turn on and off two extreme states corresponds to a linear power supply. Such as mobile phone charger, its efficiency is generally more than twice the linear power supply. Distinguish between two kinds of power: switching power supply is very small and very light, there is a very small transformer, and linear power is relatively heavy, the transformer is a major part of the power supply. Is a very complicated technology, very promising.
