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: Power amplifier with a good power or good switching power supply?: Cow is better. Switching power supply resistance is low, transient good, but the impact on the sound quality.

Q: 24-volt switching power supply why leakage: 1, the ground has two y capacitors Neutral grounding way connection, (fire --- || --- --- ---| --- zero) In this way if the socket is good grounding is no problem, But the socket ground if the virtual connection, this time on the line with 110V (may be higher and lower) equivalent potential, if the electrical appliances are metal shell ground, it is possible that the entire shell are charged, the pen will be bright, Ma hand.

Q: What is the difference between an open switching power supply and an ordinary switching power: Open-type switching power supply generally refers to no sealed shell, and can be cooled by natural air-cooled, all the wind a program to do the power of open switching power supply can do more

Q: Why switching power supply with two series capacitor filter, with a can you: The two capacitors are used in series because the circuit uses a symmetrical dual power supply, and the capacitive + - connecting pin is the common ground of the circuit. Computer power is such a circuit, you can see there are two 220v470u electrolytic capacitors. The use of symmetrical power supply is to reduce the use of the circuit voltage, improve circuit safety.

Q: What is the difference between non-isolated flyback switching power supplies and isolated switched-mode power supplies.: There is no transformer in the non-isolated circuit. The so-called forward and the flyback is very good, the flyback transformer has energy storage, transformer primary and secondary with the same name on the contrary, drive signal conduction, primary conduction, secondary cut-off, energy storage; drive signal cut-off, primary Cut off, secondary conduction, pass. While the forward transformer is no energy storage, and the primary and secondary are in phase

Q: Four-way monitoring switching power supply is not just a camera circuit can all the way? Or is there a problem with the equipment or line? The camera will appear short-term flash, shaking, black screen phenomenon. Now is the four cameras are connected to the positive and negative, the power is 12V6.3A, plus a small 12V1A power alone access to a camera, the results of a separate shine, the last black screen. The original problem of the camera or a problem, no problem or no problem. And the fault is short, I suspect that the camera problem, but the manufacturers that no problem. Depressed ah! Which a master to help one.: The best is to buy a single 12V1A power supply and then 220V directly to the camera in front, then take 12V1A power supply, so no power attenuation

Q: Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.: The same winding the same diameter of the conditions, the greater the air gap, the smaller the amount of inductance. The larger the air gap, the lower the permeability, the smaller the inductance.

Q: How to constant voltage switching power supply into a constant current, how to rectification ?: Can not be converted, because the work of different ways to work the object is also different. Due to constant voltage source and constant current source has different circuit characteristics, it can not be replaced with each other. The respective circuit characteristics are as follows: Constant voltage power supply (regulated power supply): can be a constant output voltage to the load power supply. The ideal internal resistance of the constant voltage power supply is zero and can not be shorted when used. Constant current power supply (constant current source): A power supply that can output a constant current to the load. The ideal internal resistance of the constant current power supply is infinite and can not be opened when used.

Q: Why should the switching power supply feedback the winding power supply?: The switching power supply is divided into self-excited and it is excited. The self-excited need is only the feedback winding to provide an excitation pulse signal. And it is excited because it requires independent control chip to work.
