Kas ir vaids ar the spriegums kritums pēc iekraušana the switching power supply?
Iespējams problēmas: atgriezeniskā saite cilpa pastiprināšana ir nav pietiekami, VCC spriegums is high power supply capacity is not enough CS feedback is too large, etc., but also specific problems to be analysed specifically. Komutācija barošana padeve is izmantošana moderns jauda elektronika tehnoloģija, kontrole pārslēgšana caurule ieslēgšana un izslēgšana laiks attiecība, to uzturēšana a stabils izeja spriegums of a power supply, komutācija barošana padeve is vispārīgi komponēts of impulss platums modulācija (PWM) kontrole IC and MOSFET.
Ar attīstība un inovācija of power electronics technology, it makes the switching power supply technology is also in constant innovation. At present, switching power supply with small, lightweight and high efficiency is wide wide used in all electronic equipment, is today's electronic information industry rapid development of an indispensable power supply method.
You can start from the power supply self and external circuitry. First measure the switching power supply input formation is normal, most of the power supply input is is 220V, if the low is too much, you can first input power supply supply voltage.
Ja it is too low, you can first repair the input power supply spriegums is normal, and then measure the output voltage. Still not normal, remove the switching power supply output line, such as voltage recovery is the load fault, such as the output is still paper. If the output is still paper, the switching power supply self is faulty. Ir ir vairāki veidi of spriegums izeja pārslēgšana barošana padeve, check vajadzētu jāatvieno no visiem izeja, kad apstiprināts par slodze kļūme var būt kad slodze kļūme ir apstiprināts, the load can be accessed one by one, and if the voltage samazinās kad the load is access, it is the failure of this road.
