- Q:Switching power supply (AC-DC) use notes and tips
- 10, switching power supply in the factory to 100% full load aging, the general use of power control within 80% or in accordance with the requirements of the instructions. According to the temperature curve to develop power efficiency. The general temperature is increased by 10 ° and the capacitance life is reduced by half.
11. Before using the switching power supply, make sure that the input voltage specification (110VAC or 220VAC, 24VDC or 48VDC ...) matches the nominal value of the switching power supply used.
- 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.
- 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:Switching power supply, constant current power supply, resistance to the power supply where the benefits?
- Roughly compare it
Switching power supply, RC power supply ----- these two, the general switching power supply to do greater power; resistance capacity of the power is generally micro power
Constant current power supply and the above species is not compared, the switching power supply can also be done
- Q:Working principle of small switching power supply
- Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for transformer, resulting in the required group or groups of voltages! The reason for the high frequency AC is that the high frequency AC is much more efficient than the 50HZ in the transformer transformer circuit. So the switch transformer can be done very small, and the work is not very hot! The The cost is very low. If not 50Hz into high-frequency switching power supply does not make sense
- Q:What is off-line switching power supply
- You can not take the power, with their own battery switching power supply
- Q:What is the difference between switching power supplies and transformers?
- Transformer can change the voltage, and switching power supply is not a
- Q:What is switching converter and switching power supply?
- Switching converter is a core component of modern energy conversion technology. It is also a basic component of all kinds of switching power supply, inverter, UPS, photovoltaic power generation, wind power generation and LED lighting. It is widely used in electric power, communication, home appliances, railway transportation , Automotive electronics, industrial control, instrumentation, aviation, aerospace, navigation and other fields.
- Q:Touch switch failure when switching power supply
- You this problem I help you in the big bit forum post, and so the master to provide more detailed solution.
If you have the answer, the first time to inform you, you can leave a mailbox. If the problem is more urgent, you can log in to the forum and then search for your title to see someone else's answer is also OK.
- Q:What is the use of transformer shielded grounding in switching power supply?
- Internal shielding: between the primary side and the secondary side to increase the winding or copper foil, leads to one end of the original side of the work above the main purpose is to the primary side of the common mode interference signal through the shield back to the source of harassment, if not the shield Layer, there is a common mode interference signal will be passed between the primary winding between the interlayer capacitance to the secondary side, causing the output of the EMI problem.
External shielding: in the transformer outside the magnetic core and winding coated with a layer of copper foil, this layer of copper foil to be closed to form a ring circuit. The leakage magnetic field of the transformer is not closed inside the core, but leaks into the external space. In the high frequency application, the strong leakage magnetic field will induce the voltage in the closed loop of the input and output ports, resulting in EMI test results deteriorate. If there is an external shielding layer, according to the principle of electromagnetic induction, the shield layer will induce the current, the formation of the opposite magnetic field, offset the transformer leakage magnetic field effects.
