- Q:Explain several protection of switching power supply OCP; OLP; OVP; OTP; ESD; UVLO
- In order to switch the power supply stability and reliability, usually set many types of protection.
- Q:Switching power supply control chip selection: UC3844, VIPER series, topswitch series. What is good?
- Cost requirements for high UC3844
The size of the requirements of the high TOP
Viper not used, not stand
- Q:Note the operating conditions of 220V voltage and the order of switching power supply
- Power failure - electricity - lock - seal ground - warning signs
- Q:Give you a switch on how to look at it is isolated and non-isolated?
- Isolated for high-pressure exchange, a transformer, the transformer is mostly core, but also useful magnetic ring
Non-isolated generally low-voltage direct current, no transformer, there is an inductor, high-power multi-purpose magnetic ring, low-power inductance with more
- Q:Switching power supply management IC FB, CS, DEM specific what role ah
- FB is the voltage feedback, CS is the current feedback, DEM do not know, it is best to send the chip, the different circuit function is not the same. Such as constant current output circuit FB is the current feedback!
- Q:The output voltage of the switching power supply decreases as the load increases
- This step by step, look at the power output power is not lower than the rated power of the motor, did not continue
Your power supply is not a long output line, no continuation
Appropriate increase the load of the motor to see if the power can work, you can continue
Long time to work for a period of time to see, no problem, that power no problem
Voltage drop a little, if there is no impact on the normal use is acceptable, if the transformer down more powerful
- Q:Switching power supply, starting resistance is very hot, no output
- You ask the question is the common problem of switching power supply, you have to study the power schematic diagram! Practice basic skills.
- Q:Switching power supply transformer core how to choose?
- 1, according to the power to select the core size, combined with the layout of the whole board to select the core shape, according to environmental factors, switching frequency selection core material, according to the feasibility of core procurement, raw material costs to choose, consider the transformer processing technology Requirements, select the skeleton core shape, the output power of the size of the core material is mainly to see the size of the cross-sectional area of the core, the number of windings and the number of windings and so the main look at the size of the window area of the core material, in fact, Its best application. That is, when you choose to use, Yang long, to avoid its short, so that better design, select the core material, the first to determine the basic parameters of its core material, that is, according to your specific use Environment to choose whether the PC40 or PC50;
- Q:Led switching power supply used in what place
- Used in LED lamps, the general use of more street lights, or some relatively high-end LED lamps, because a switching power supply at least dozens of pieces to hundreds of pieces of the price.
- Q:24v switching power supply can do car battery charger?
- 24v switching power supply can do car battery charger, but also need to limit the charging current measures, do not know that the switching power supply can output the current is enough, too small, the charging time will be very long.
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.
