Q: Switching power supply COM how to connect: Generally grounded. The The The The Specific instructions, marked

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: Neighborhoods! Control transformer and switching power supply of the difference, for occasions, advantages and disadvantages: Control transformer output for multiple groups of AC, usually AC: 36v, 24v, 12v, 6.3v, mainly for the lathe control system and some other need 36v coil voltage control occasions; switching power supply also has multiple output, but the output is After the DC voltage regulator, usually DC: 48v, 24v, 12v, 5v, 3.3v, etc., mainly used for some need more than one DC power supply place, such as: the computer power supply is more than one group of DC output switching power supply, It has 12v, 5v, -5v, 3.3v and other sets of output; electric bicycle battery charger is the switching power supply, usually the output DC voltage of 48v DC, used to charge the battery, there are 24v.

Q: I copied a circuit board, 7W switching power supply, line and the original circuit is exactly the same, that is slightly different alignment, no power after the output. I made two boards, are the same ask, ask the master, where is the problem? How to deal with?: There may be a transformer problem, you have measured the inductance of two transformers is the same, flyback switching power supply is the core to stay in the gap.

Q: Why should go through the cross - straight - pay - straight conversion, rather than directly after the transformer buck after rectification, filtering, switching power supply is not a way to reduce costs? Parallel power supply is significantly better than switching power supply, why no one tried to do one?: Switching power supply does not only play the role of power switch, but also can be set to sleep, the role of deep sleep

Q: Would like to ask the switch power supply in the end is what role?: Open on the electricity, turn off no electricity, and then fine that is open after the internal power supply channel can work.

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?: Power density ratio; soft start; DC-DC conversion, rectification, EMI, intelligent control.

Q: What is the linearity of switching power supply: Different power supply, linear adjustment rate is different Constant pressure source: Linear adjustment rate: the rate of change of the output voltage within the specified input voltage range; ΔV / V = (V - V1) / V * 100% Load rate: change in load within the specified range, change rate of output voltage; ΔV / V = (V-V1) / V * 100% A constant current source: Linear adjustment rate: the rate of change of the output current within the specified input voltage range; ΔI / I = (I - I1) / I * 100% Load regulation: change in load within the specified range, change rate of output current; ΔI / I = (I-I1) / I * 100%

Q: What is off-line switching power supply: The so-called off-line power supply, the English name "Offline Power" that is isolated power supply. Off-line switching power supply, also known as isolated switching power supply, is an AC-DC converter circuit. AC and DC are isolated by transformer. In some laboratories or high demand occasions, for the safety of the experimental staff, the experimental input power is generally used 1: 1 frequency transformer and the mains to isolate, so that the laboratory laboratory personnel regardless of which line encountered The root line will not have the risk of electric shock, because the isolated power and the earth is not connected. In industrial control equipment, it is sometimes necessary to isolate the power supply lines between the two systems, such as isolating ground noise, isolating high common mode voltages, etc., using a DC converter with a transformer to separate the two power supplies They are independent of each other, in order to achieve the above purpose! Each module is powered separately to prevent a module from damaging other modules due to high voltage discharge or other causes. The purpose of this can be to ensure that each module is working independently and undisturbed.

We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
