- Q:Switching power supply gnd is doing
- Is a place for the application of the assumption that for the power supply, it is a negative power supply. It is different from the earth. Sometimes need to connect it with the earth, and sometimes do not need, depending on the circumstances
- Q:Switching power supply isolated design, what is the meaning of isolation?
- Isolation is achieved through the transformer, in the design of switching power supply when the use of isolation transformers (primary winding and secondary winding is not connected), so that the output of the power supply and the input power is not common, dual isolation is the switching power supply of two Road output are not common.
The advantage of isolation is that the primary side of the transformer or the side of the circuit when there is a short circuit will not burn the other side of the components.
- Q:24v switching power supply can do car battery charger?
- Can, but need to be part of the conversion, coupled with constant current control circuit, different battery charging current is different, such as 165AH battery do not use 16.5A current, 14V charge 10 hours
- Q:High power high frequency switching power supply with what rectifier
- Input level with ordinary rectifier can be, the output stage recommended with silicon carbide diodes
- Q:Switching power supply, 2SC3320 switch tube is always burned
- In general, the main reasons for the damage to the power switch tube are the following 13:
1. Soft start circuit failure
2. Switch tube integrated circuit board anti - peak absorption circuit failure
3. Positive feedback is too strong
4. Timing capacitor failure leakage
5. Decoupling Capacitor Failure in Regulating Circuit
6. The negative feedback loop of the regulator circuit
- Q:What is the problem with the switching power supply?
- IC is generally the auxiliary power supply is a problem, the relevant components to check:
R8, R9, Q3, Z1, D5, R14, and transformers. Finally, U2.
The main thing you want to look at the voltage of the IC VCC pin is not within its specified range, if the IC problem, if not, from the C1 positive step by step to find over.
- Q:24-volt switching power supply why leakage
- 3, the real induction power, as long as the power supply, whether it is power or switching power supply, the general transformer high voltage low side will have an equivalent capacitor, can be seen as the first two conditions, there will be a trace of leakage current, This situation can not be avoided.
- Q:How does switching power supply eliminate ripples and burrs?
- Low frequency ripple burr suppression of several commonly used methods:
A, increase the output low-frequency filter inductance, capacitance parameters, so that low-frequency ripple reduced to the required indicators.
B, using feedforward control method to reduce the low frequency ripple components.
High-frequency ripple to suppress the purpose of the glitch is to provide high-frequency ripple path, commonly used methods are the following:
A, to improve the switching power supply operating frequency, in order to improve the high frequency ripple frequency, is conducive to suppress the output high frequency ripple.
B, increase the output high-frequency filter, can inhibit the output high-frequency ripple.
C, using multi-level filtering.
- Q:What is the component stress in the switching power supply?
- Component stress, popular stresses that the components can withstand the maximum voltage, current, temperature and so on. Component stress testing is usually a destructive test.
Do not know if you can understand.
- Q:Buy switching power supply should pay attention to what
- Consider the use of the field of switching power supply, of course, first of all pay attention to the output current, voltage, frequency, there are several output, the output voltage range, the use of environmental humidity ah, and the size of the power supply size and other technical requirements, you need to switch Power, you can go to Wuhan Crystal Kai source Technology Co., Ltd., this company is specialized in the production of switching power supply, good quality.
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.
