- Q: 12V7A motorcycle battery can not use 14V3A switching power supply charge
- Completely, the charging time is 3 hours. If the adjustment to 15 volts is also OK, the charging time is shortened.
- Q: 2014 low-frequency transformer is now the future is ok, the feeling is now doing more switching power supply, the last low-frequency transformer will be replaced
- Can not replace, in the audio amplifier, high voltage transformer and other fields, or have a unique advantage. Low-power silicon steel transformer transformer basic prospects bleak, quality is not good, and gradually disappear. CCC seems to make life difficult.
- Q: Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,
- T2: high frequency transformer R11: constitute the RC filter circuit R12: current limiting effect D6: auxiliary power supply rectifier C2: filter capacitor D5: and R7 and C5 constitute the absorption circuit, which absorbs the instantaneous spikes of the switch U1: drive the chip U6: optical coupling circuit, the main feedback loop. The main principle of this circuit diagram: AC input, through the EMC filter bridge rectifier filter, and then through the drive chip control switch and then drive the high-frequency transformer, secondary AC and then re-rectifier filter output. Output after the stage through the comparison, optical feedback, adjust the PWM duty cycle, control output stability.
- Q: Switching power supply TL431 what role, I did not find the circuit in 431 the corresponding circuit
- Capacitor in the role of the circuit: with blocking DC, connected to the exchange, to prevent low-frequency characteristics,
- Q: What is the core of switching power supply design?
- The design core is of course switch and switch transformers
- 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: What is the definition of the maximum discharge current, battery backup time, and discharge time? Always confused, when the calculation is always wrong ... ...
- What is your battery capacity and how much you become a high voltage There is also an accurate calculation of the discharge current of the battery and the attenuation of the discharge
- 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: Switching power input is marked with 220V AC, 36V output, but the actual input voltage is 238V, the output of the switching power supply affect it? Will it damage the switching power supply? Do not know the reason is not the voltage, power after a period of time (10 minutes), the switch power suddenly no output, and the display is not bright, switching power is not already broken? Guiqiu prawn to the doubts!
- 238V on the open power supply no effect, the general AC85-265V; What is the load on your switching power supply? Will it be the cause of the load? The indicator light does not shine is likely to switch the power supply is broken, or that is the input power is cut off,
- Q: Will the switching power supply fake load how to calculate?
- Switching power supply fake load, the main purpose is to overcome the no-load or light load output instability. And the output is unstable, the primary D is too small, the energy is not open is the secondary overshoot voltage or feedback current is too large, forced IC to reduce D;
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.
