Q: Switching power supply circuit will ring what will happen: Will not be regulated, the outcome is their own damage or damage to the load.

Q: Power amplifier with a good power or good switching power supply?: R-type transformer is best, ring type, switching power supply transient response is not enough, open-loop can be used, but the effect is poor. Now there are dedicated power amplifier switching power supply, the main features are: resonant switch circuit; (and the same effect as the transformer sine wave effect, very little interference, the car amplifier has been using resonant circuit). Open-loop output, not regulated output, no response time. Light weight and high efficiency. R-type transformer is a dry-type transformer products in a rookie. The core of the use of different width and width of the cold-rolled silicon steel strip made of high-quality round, and cross-section was round, no cutting can be wound. Therefore, the resulting transformer has no noise, small magnetic leakage, no-load current is small, iron loss is low and high efficiency; and because the coil is cylindrical, the length of the copper wire per lap is short, so the internal resistance is small and the copper consumption is low , The temperature rise is low, the overload fluctuation is small, the explosive force is better than the toroidal transformer; In addition, the primary and secondary coil adopts the skeleton made of flame retardant PBT engineering plastic, so that the electric resistance is high, the flame resistance is good Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply

Q: How to make the switching power supply does not delay power: Use a relay to control the output of the switching power supply.

Q: Is switching power not power? Why should the word "switch" be added?: General power supply, such as 220V of the electricity plus a common transformer (power frequency transformer) coupled with the rectifier rectifier and capacitor filter has become an ordinary power supply. Early power supply are. Is such a. After the line with a linear regulator circuit has become a power supply. But this power supply on the input voltage requirements are higher, the larger the voltage input after the wave may not reach the adjustment effect , While the high pressure when the pressure drop in the adjustment device, the power efficiency is low.

Q: Recently to be an automatic lift, switching power supply with the touch mode control and found that sometimes failure, into the frequency transformer is not the problem, the problem is only with the switching power supply, would like to ask if there is nothing to improve this Problem? Switching power supply is bought directly outside the back. There is not much change: Plus 4700 microfarads and 104.103.10p capacitors at the output and the input of your control circuit board In the touch of the power input side of the string into a 10 ohm or so resistance, put a 220 micro capacitor before the capacitor, put two 104.103, but also the resistance into inductance.

Q: What is the output of this group? If the power supply to the 48V, is not +24 V termination of the electrical 48V + input, -24V termination of the electrical 0? is this okay? Voltage difference is 48V ah? Thank you very much!: Any voltage is relative to the reference point, +24 V relative to the ground potential difference is 24V, and for -24V is 48V Then -24V to the ground as a reference point is -24V But note that some switching power supply + - output current is different, to check the product manual.

Q: AC-DC switching power supply, how to connect, input AC, AC, FG three ends: but generally follow the principle is: FireWire to pass through the circuit breaker as a protection, zero line generally connected to the zero line card. FG ground wire.

Q: Switching power supply maintenance methods can be divided into several steps: ?2, the first step is completed, after the power is not working properly, and then to detect the power factor module (PFC) and pulse width modulation components (PWM), access to relevant information, familiar with the PFC and PWM module each foot function and Its modules work properly prerequisites.

Q: How to constant voltage switching power supply into a constant current, how to rectification ?: You give specific parameters, I give you the device model and practical circuit diagram (provided that the output current can not be too large, the load impedance can not be too high).

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.
