Q: What is the component stress in the switching power supply?: Component stress, including voltage stress, current stress, temperature stress, power consumption

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: There are three problems need to be identified, 1 is the power output power in front of how much, if small, can not be changed, only for the front of the power; 2 is 200 meters diameter, if too thin, a little current Will produce a lot of pressure drop

Q: How are two ac inputs connected to the socket? G1 and G2 and FG is not connected together, and then connected to the chassis? thank you: According to your instructions to write your power is two output, Two AC terminals through the power cord can be directly connected to the socket, no positive and negative points; FG is the power and the earth (that is, the chassis) connected; In the order you say, G1 and V1 are a group (G1 is this negative, V1 is positive); G2 and V2 are a group (G2 for this road negative, V2 is positive); Note: FG and G1, G2 can not be mixed!

Q: Switching power supply (AC-DC) use notes and tips: Power Usage Precautions: First, the metal shell Power cord and the shell is generally connected with the ground (FG), to be reliable grounding, to ensure safety, can not be mistaken to the shell connected to the zero line. ??Second, before the installation is complete power test run, please re-check and proofread the wiring on the wiring, make sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current value is correct Before they can run. ??Third, for high-power LED switching power supply, there are three or more than three "+" input terminals and "-" output terminals, in fact they belong to an output electrode, just to make the user easy to connect, and multiple terminals Respectively, in the internal and then together.

Q: What is the basic principle of switching power supply?: The basic principle of switching power supply is: The 220v 50HZ exchange, finishing 300v DC, the switch and the oscillation circuit, so that it becomes 40KHZ or higher frequency square wave voltage, coupled through the high-frequency transformer to the secondary, so that the secondary to get the required voltage The That is, the actual switching power supply, is the high-frequency transformer.

Q: AC-DC switching power supply, how to connect, input AC, AC, FG three ends: but generally follow the principle is: FireWire to pass through the circuit breaker as a protection, zero line generally connected to the zero line card. FG ground wire.

Q: Is switching power and transformer the same thing?: This is not a matter of time, the switching power supply is to control the power supply, the transformer is to change the size of the voltage, the transformer in the case of power to control the voltage.

Q: What is the meaning of the magnetic ring color in the switching power supply?: Switching power supply used in the magnetic ring generally there are two, one is the high permeability of the green ring, used in the input and output. The color is green. Do common mode inductance use. One is power type. If it is black or blue, is generally iron silicon aluminum. If it is blue-green material is -52 core powder. If it is yellow and white is -26 material iron core, do energy storage inductors use. There are some more special applications are transformers. Drive transformer magnetic ring. Magnetic beads, dc head filter magnetic ring. Division I is a professional transformer. There is not clear you can talk to me.

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.

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?: Switching power supply of the actual, 24V, etc.), if the PC power is generally a metal shell, with a semiconductor power device as a switch, input AC220V, Through the high-frequency transformer coupled to the secondary, is the high-frequency transformer. AC220V switching power supply refers to the input is AC220 volts, a power mode into another form of the main circuit called the switch converter circuit; change with automatic control closed-loop stable output and protection is called switching power supply. But also at any time to check the current power supply equipment, generally from the insulation effect. Through the switch tube and shock circuit, such as electronic rectifier with the 13001--13007 series, the basic principle of switching power supply is: the 220v 50HZ exchange,
