- Q: I am now learning switching power supply, read some of the information in the "work in the CCM state of the flyback power", because of this do not understand, would like to ask the power of friends can give to explain, very grateful! As well as the principle of positive and reactive work mode? And tell me what I want to learn switching power supply only little knowledge of what I now learn from?
- The following are the same as the " DCM is characterized by the use of two switching cycles between the inductor current to the dead zone. Compared with the continuity mode, the circuit design is easier to achieve, because of its conduction when the current is zero, so do not have to consider the boost diode reverse recovery current , The requirements of the diode is relatively low. Obviously, in the same average input current, DCM requires a higher peak inductor current, which requires the use of large power devices. Due to its large range of current changes, the higher the peak, the inductance of a larger core. Heat loss is large. Harmonic to true degree is also larger than the continuous mode, so the current discontinuity mode - only used for relatively small power switching power supply.
- Q: What is the PWM high-frequency switching power supply
- PWM-type high-frequency switching power supply is the use of pulse width modulation (PWM), referred to as pulse width modulation, is the use of microprocessor digital output to control the analog circuit is a very effective technology, widely used in measurement, communication Power control and transformation in many areas of power. PWM switch regulator or steady current power supply basic working principle is in the input voltage changes, internal parameters change, external load changes in the case, the control circuit through the control signal and the difference between the reference signal closed-loop feedback, adjust the main circuit switching device Of the conduction pulse width, making the switching power supply output voltage or current control signal is stable.
- Q: Ups and high frequency switching power supply
- UPS and high-frequency switching power supply The main difference: High-frequency switching power supply, refers to the use of power switching devices, at high frequencies through the converter for energy conversion power. High-frequency switching power supply (also known as switching rectifier SMR) through the MOSFET or IGBT high-frequency operation, the switching frequency is generally controlled in the 50-100kHz range, to achieve high efficiency and miniaturization. UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption. Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.
- Q: Who can help me choose a switch power supply model 220V AC / 10V DC
- 20VAC is the input voltage, 10Vdc is the output voltage ah! There is no model of the power is this specification, are designed according to the needs of this!
- Q: Now I want to buy a larger power test power, about 1KW. I have no money, so I want to buy a switching power supply, so that you can save a lot of money, but do not know can not accept the emotional load
- Not necessarily So that the output if it is emotional load will affect the module loop So it may cause the switching power supply loop is unstable
- Q: UPS and switching power supply what is the difference
- China's household appliances operating voltage is AC 220V. UPS and switching power supply main difference is: UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption. Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.
- 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.
- You are not a flyback transformer only done once the air gap concluded that there may be two of your core wrapped around the loose is not the same, anyway, it is impossible under the same conditions, the air gap to increase the amount of inductance but large.
- Q: The hands of a switching power supply, the use of 2SC3320 switch, the output is 24V7A, after adding the load will always burn 2SC3320 switch, no load no problem, how is it, there are drawings, that expert help to see, thank you
- The power switch works in the switch state, the cause of its damage, in addition to over-current over-voltage, but also taking into account the duty cycle, that is, saturated conduction time and cut-off time ratio.
- Q: I have an output voltage of 3V, 500MA switching power supply, would like to change the output voltage of 5V charger specific parts to change the value, such as feedback resistor, switch transformer (there are two).
- Replace the output transformer can be, but must be the same with the resistance value should be no problem! 11
- Q: Computer host switch power supply how much money?
- This is cheaper, more than 20 dollars on the line
