Q:Is the DC power supply a switching power supply?
Yes! Modern switching power supply there are two: one is the DC switching power supply; the other is the AC switching power supply. DC power supply that is DC power supply, is to maintain a stable current in the circuit device. Such as dry batteries, batteries, DC generators and so on. DC power supply has positive and negative two electrodes, the potential of the positive pole is high and the potential of the negative electrode is low. When the two electrodes are connected with the circuit, the potential difference between the two electrodes can be kept constant, so that the positive electrode Negative current.
Q:What is the difference between Switch Mode Power Supply and electronic switch? Where are they?
Switching power supply is a large class, usually we say that the switching power supply is AC variable DC power supply, but in fact, including DC variable DC, DC variable AC (inverter) should belong to the switching power supply.
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,
Q:I do not understand the transformer should only work in the alternating voltage, but the switching power supply to the PWM IC output terminal connected to the primary input PWM IC has been rectified filter DC. Is the PWM modulation obtained by the high frequency of the exchange?
2, PWM (pulse width modulation) is higher than 50Hz frequency, so that the transformer can be smaller, and the work efficiency will be greatly improved.
Q:Switching power supply
Switching power supply is usually divided into AC / DC, DC / DC, DC / AC and other types. Popular is to convert a voltage into a specific voltage for the needs of electrical equipment. Such as car switching power supply is the car's 12V DC voltage into 5V or other voltage for the use of equipment. Commonly used mobile phone charger (also switching power supply), computer power and so are switching power supply.
Q:Output 12V2A switching power supply, I would like to change to 12V5A, is not the transformer changed on the line
Not to change the transformer, but should be the transformer capacity increases
Q:Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,
This is a single-ended flyback switching power supply circuit, in this switching power supply, T2 is a high-frequency transformer, the role of voltage conversion, R11 is the starting resistance of U1, the input voltage of 85 - 2-265 AC, the choice should be in the 1--2W, 150 - 330K resistance between, usually need to use multiple resistors in series, otherwise it is easy to damage. R12 is the current limiting resistor of the switch, but also U1 overcurrent current detection resistor, the output short circuit when the voltage drop on the resistor will become high, U1 protection to stop the output drive signal. D6 is the transformer provided to the U1 supply voltage rectifier. C2 is the main filter capacitor, usually with electrolytic capacitors, voltage is greater than the maximum voltage input of 1/3, the capacity of about 1W / micro-law output. Q1 is the FET, is the switch tube. Generally also mos. D5 and R7, C5 are connected to the transformer primary to form the transformer spike voltage absorption circuit. When the switch is turned off, the moment the transformer will have a very high induced voltage generated, this circuit can be absorbed by this spike voltage (or is limited to a safe Of the range). Also called DRC or RCD spike voltage absorption circuit. U1 is the switch tube drive circuit, here should be a PWM integrated circuit, also known as pulse width modulation, is the English "Pulse Width Modulation" abbreviation, referred to as pulse width modulation. U6 is a photocoupler,
Q:What is the industrial switching power supply
Switching power supply is divided into civilian-grade industrial grade military grade of course different levels of power, safety requirements, performance requirements, insulation level and so on are not the same requirements, the same level of power also look at what work environment, require different power level The standard is different. Need power to find me
Q:What is the difference between non-isolated flyback switching power supplies and isolated switched-mode power supplies.
Although the optocoupler is also a way to isolate, but in the switching power supply are generally speaking of the voltage isolation. Two isolation is different: the role of optocoupler is mainly to prevent the back of the DC high voltage feedback to the control circuit in the burn control circuit; isolation transformer role: 1, play a role in isolation 2, from the role of filtering; The role of pressure
Q:Ming Wei switching power supply is why use?Ming Wei switch what to use, I see he is a circuit board, five wiring of the mouth, he used in the equipment what is the use? What is his general effect on the equipment?
AC variable DC, high voltage to low voltage for the equipment circuit to do power use.
