Q: What is the relationship between the output voltage of the switching power supply and the PWM signal?: First of all, what is your circuit topology? Is BUCK, or isolated rebirth is it? Different circuits, the answer to your question is different. However, a large range can be explained as such. The larger the PWM duty cycle, the stronger the output load. (That is, the output voltage * the greater the output current.) You better, or look for the corresponding topology of your circuit information, find the formula, so good to understand some.

Q: Switching power supply isolated design, what is the meaning of isolation?: In simple terms, isolation means that electrical insulation is insulated from each other and can not be directly energized. The purpose of isolation is generally for safety reasons, and not isolated in the security is not guaranteed (the internal circuit is a channel, will be direct conductivity), but not isolated also has its benefits, that is, the line is simple, relatively isolated products It is more efficient.

Q: Can notebooks have an external switching power supply?: Note: Notebook boot links are different, resulting in different welding, the contact directly on the line, fixed style can also be welded directly, the more troublesome cable, so you need to determine the two contacts are off the switch, you can Try again and again, and then find a point to connect, connect on the line.

Q: Switching power supply: Switching power supply is usually divided into AC / DC, DC / DC, DC / AC and other types. Popular is to convert a voltage into a specific voltage for the needs of electrical equipment. Such as car switching power supply is the car's 12V DC voltage into 5V or other voltage for the use of equipment. Commonly used mobile phone charger (also switching power supply), computer power and so are switching power supply.

Q: 2014 low-frequency transformer is now the future is ok, the feeling is now doing more switching power supply, the last low-frequency transformer will be replaced: 1, low-frequency transformers will not be replaced; 2, low-frequency transformer without switching power supply pulse interference; 3, low-frequency transformer with a variety of power grid pulse interference; 4, low-frequency transformer with switching power supply can not counter the anti-surge ability, especially lightning; 5, low-frequency transformer production of linear power supply has the best introduction of ripple performance; 6, low-frequency transformer output can use low-voltage switch chip, with isolation at the same time also has a high efficiency; In the industry, low-frequency transformers can be a good isolation from a variety of high-power inverter, servo, SCR control caused by interference.

Q: How the phase margin and gain margin of the switching power supply are measured: 1. Requires a dedicated spectrum analyzer. The instrument (such as the Fluke Spectrum Analyzer, HP, etc.) can automatically scan the BODE of the measured power supply.

Q: 24v switching power supply can do car battery charger?: Due to the battery resistance is very low, increase the power output voltage, charging will lead to excessive charging current, the power switch tube will be burned due to excessive current, it can not use the computer switching power supply to the car battery

Q: What is the core of switching power supply design?: Power density ratio; soft start; DC-DC conversion, rectification, EMI, intelligent control.

Q: The hands of a switching power supply, the use of 2SC3320 switch, the output is 24V7A, after adding the load will always burn 2SC3320 switch, no load no problem, how is it, there are drawings, that expert help to see, thank you: The power switch works in the switch state, the cause of its damage, in addition to over-current over-voltage, but also taking into account the duty cycle, that is, saturated conduction time and cut-off time ratio.

Q: Switching power supply, what is the hard switch? What is a soft switch?: The so-called hard switch, power immediately after the output voltage, the soft switch is the voltage rise after the voltage rise output.
