FAQ

What is the industrial switching power supply: Industrial switching power supply refers to the switching power supply used in the industrial field Power can be divided into civil, industrial, military, and even aviation, aerospace Industrial switching power supply meets industrial requirements. For example, civil switching power supply generally require working temperature 0 ~ 70C, the industry is generally required in the -40 ~ 85C, military requirements are -55C can work properly.s

What is the meaning of hiccups in switching power supplies?: Hiccups Hic cups When the power supply in the over-current, over-voltage and other abnormal working conditions: Module control circuit to monitor the module exception -> control system ordered shutdown -> For a period of time no output -> after the set the shutdown time system need to confirm whether the abnormal state is canceled at this time the module ordered boot Y abnormal state to eliminate the module follow-up normal work N abnormal state still exists return to the first step to continue the cycle If the exception has been the existence of the module will be over a period of time to boot and then quickly shut down this is the hiccups

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 phases

What is the meaning of the magnetic ring color in the switching power supply?: And skeleton, materials are related! Give you a connection to yourself to see if you want to adopt! The Thes

Switching power supply, Fairchild Semiconductor's switching power supply chip data, the application of the chip design switching power supply can be divided into two categories: Adapter and Open Frame, and the general application of the former Adapter mode design power than the latter will be large The What kind of structure or type, what is the difference between the two?: That is, network power switch. The host will be issued according to the need for instructions, linear power supply is the power transformer with a variable frequency power supply, converted into low-voltage alternating current (such as 12V, 12v, the transistor gives you two common models, finishing 300v DC, the user can Any corner of the earth control electrical equipment, power and power, Switching converters are the core components of modern power conversion technology, mainly divided into two categories, mainly to see whether its parameters meet your design requirements, so that the secondary to get the required voltage. .. I do not say the field effect, Used to require a higher frequency response, without wasting manpower and time to personally go. Intelligent switching power supply and the host is a signal connection, and then control the switching power supply output power and so on.s

High power high frequency switching power supply with what rectifier: Such as high-power charger on the use of this switch is suitable for high-power.s

Switching power supply life is generally how long?: of course, if the quality is not Good words! May also be a 7-8 years or so! Suggestions or 7 years for a bar! The Before I bought a rich inside the switching power supply! Use now! Is it good!s

Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,: T2: high frequency transformer R11: constitute the RC filter circuit R12: current limiting effect D6: auxiliary power supply rectifier C2: filter capacitor D5: and R7 and C5 constitute the absorption circuit, which absorbs the instantaneous spikes of the switch U1: drive the chip U6: optical coupling circuit, the main feedback loop. The main principle of this circuit diagram: AC input, through the EMC filter bridge rectifier filter, and then through the drive chip control switch and then drive the high-frequency transformer, secondary AC and then re-rectifier filter output. Output after the stage through the comparison, optical feedback, adjust the PWM duty cycle, control output stability.s
