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:12V switching power supply measurement 13.7V normal?: Not normal, the reason may be that the voltage feedback is not adjusted.

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: Yes, the actual use of a lot. When using the attention, the output connected to a switch, stop, do not directly off the power, you must first disconnect the switch, to avoid inductive load current after the sudden change in the potential to damage the power supply. The above matters, even if other power supply, should be kept as far as possible.

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?: That is, network power switch. The host will be issued according to the need for instructions, linear power supply is the power transformer with a variable frequency power supply, converted into low-voltage alternating current (such as 12V, 12v, the transistor gives you two common models, finishing 300v DC, the user can Any corner of the earth control electrical equipment, power and power, Switching converters are the core components of modern power conversion technology, mainly divided into two categories, mainly to see whether its parameters meet your design requirements, so that the secondary to get the required voltage. .. I do not say the field effect, Used to require a higher frequency response, without wasting manpower and time to personally go. Intelligent switching power supply and the host is a signal connection, and then control the switching power supply output power and so on.

Q:UPS and switching power supply what is the difference: Ups is an uninterruptible power supply, is a kind of energy storage device, can be seen as a battery; The switching power supply is a power supply that maintains a stable output voltage

Q:Isolation switch power supply and non-isolated switching power supply advantages and disadvantages,: First of all from the name can be seen, isolated switching power supply is isolated, that is input and output is not connected (in fact, there is a small capacitor between input and output), even if the power is broken, the input voltage is not Will be added to the output, due to the input and output isolation, the input part of the noise will not be transmitted to the output part (non-switching noise), isolated power supply mostly AC-DC, is AC to DC, can also be used for DC to exchange (such as Inverter), the voltage output is generally fixed or adjustable range is relatively narrow, but the output voltage is very wide, such as the input is 220V AC, the output can be 3V, it can be 30V, it can be 3000V, it can be 30000V Non-isolated switching power supply is generally DC-DC, that is, we often say that the DC to DC, the general non-isolated power supply efficiency than isolated power supply efficiency, but because the input and output are connected between, so there is a total (BUCK) If the switch tube breakdown, the input part of the voltage will pass to the output, the boost type of the type of noise, that is, when the input voltage is noisy, it is easy to pass to the output, (BOOST) If the circuit does not work, the input voltage will go straight to the output, whether it is buck or boost type, adjustable range is wide, step-down type can generally from 0 to the input voltage (due to the circuit Voltage drop, actually less than the input voltage), step-up type can be from the input voltage to several times higher than the input voltage There is also a non-isolated circuit up and down (SEPIC), the input voltage can be higher than the output voltage, but also lower than the output voltage, and the output voltage adjustment range is relatively wide

Q:What is the difference between a switching power supply and a switching regulator?: 2, switching regulator, the key word is in the regulator, so the output of the switching power supply has a negative feedback sampling circuit, can play the role of regulation, usually switching power supply efficiency will be relatively high, the input dynamic range comparison Large, dynamic response is better, so now more widely used.

Q:New to buy the switching power supply, it should be bought fake, and after the output with the amount of output DC24V, then a small motor to 23.7, and a parallel down to 23.5, and on the 23V, and help me analyze Cause, change any solution: This switching power supply does not provide the power you want. The The Best for one. The The The regulator is too bad.

Q:Why some switch power there are two switch tube? Two transformers, one big and one small series: With a small push large, compound use, increase the power supply

Q:I have a 12V3A switching power supply. From 0V to 12V, 2V3V can start. Want to carry out voltage regulation. How to do? If you use the potentiometer to connect the kind of potentiometer. I connected to the permanent magnet three brush motor is the car with the wiper motor, the motor high and low speed adjustment. Originally wiper motor there are two blocks. Richer speed adjustment.: 12V3A switching power supply can not change the output voltage by external voltage regulator. Switching power supply PWM control technology using pulse width modulation technology to control the opening and closing of the switch, in order to achieve the stability of the output voltage. Switching power supply during operation, the output voltage changes through the optocoupler device to feedback the signal to the PWM controller, control switch drive signal pulse width, that is, duty cycle, adjust the power switch switch ratio, to achieve stable output voltage purposes. External voltage regulator potentiometer, can not be reliable access to the output signal acquisition and feedback adjustment function, it can not be achieved by an external regulator potentiometer to adjust the switching power supply output voltage.

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.
