- Q: How to identify the computer motherboard and switching power supply, restart, hard disk plug
- 1, pick up a computer motherboard, in its surrounding observation generally have two rows of pins side by side pile together, and then carefully view, the motherboard plane also note the following words:
- 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: Hello everyone, I have a switching power supply chip with UC3845, fault: turn on the power instantaneous power indicator light and then off. After the investigation did not find a short circuit phenomenon. When the shortcomings of several consecutive shortcuts on the receiving side of the two pins, the power can be activated. What is the reason for this? thank you all!
- In addition, increase the output capacitor, will only increase the impact of the starting current, no way to start. Reduce the voltage is not feasible, because it would lose their own meaning, and for a large switching power supply that can be considered a problem, wasted. Analysis of the actual current detection link and peak and power limit links, because they do not know what specific program, so do not know, the appropriate tune can be a little bit.
- Q: Explain several protection of switching power supply OCP; OLP; OVP; OTP; ESD; UVLO
- (OCP), limit the maximum output current; overload protection (OLP), limit the maximum output power; VDD overvoltage protection (OVP), limit the maximum input voltage; temperature protection (OTP), limit the maximum working temperature
- Q: What is the core of switching power supply design?
- There is no doubt that the transformer, PWM that a chip factory has been done, but turned into the most simple
- Q: The voltage is too low to refer to the INPUT voltage range below the switching power supply
- How little, but not large, because the switching power supply is 110 volts or 220 volts input, but the output voltage is regulated output power, so no harm, do not worry
- Q: Switching power supply OLP and OCP these two are the same concept?
- Not the same concept. OCP is overcurrent protection, many electronic devices have a rated current, not allowed to exceed the rated current, or will burn out the equipment. OLP is overload protection, to prevent the main power lines due to overload caused by overheating protection and installation of overload protection equipment.
- Q: When switching power supply is the most efficient
- According to design parameters set. Under normal circumstances, full load time is higher than the no-load.
- Q: For the specific parameters for the requirements (power: 350W or more working voltage: DC 300V) switch switch power supply which are commonly used? To say that there are specific places in Jinan where to sell? Anxious ~
- IGBT tube is the most commonly used IRGP20B60PD. MOS tube is the most commonly used IRFP450, IRFP460. Transistor is the most commonly used 2SK2850.
- Q: Why should the switching power supply feedback the winding power supply?
- The chip needs a DC power supply to work. At the beginning of the boot, most of the power supply through a power resistor will be 300V DC high voltage step-down to provide to the chip. When the chip outputs multiple pulses, the feedback winding can provide normal power. Because in the normal work, the chip power consumption is also taught. Direct use of resistance buck, it is easy to lead to work instability. Therefore, it is the type of power supply feedback circuit to send the way to work.
