LED Switching Power Supply Conditions
Sep 20, 2018| Cov ntsiab lus thiab cov yam ntxwv
Peb tej yam kev mob rau LED switching fais fab mov
1, hloov: lub zog hluav taws xob hluav taws xob ua haujlwm nyob rau hauv lub xeev hloov pauv hloov ntawm lub xeev linear
2, siab zaus: lub zog hluav taws xob cov khoom siv hluav taws xob ua haujlwm ntawm cov khoom siv hluav taws xob ntau dua li nyob ze ntawm qhov tsawg zaus ntawm lub hwj chim zaus
3, DC: hloov hluav taws xob tso zis yog DC hloov AC
LED switching fais fab mov muaj ib tug Circuit Court los tswj lub switching tube rau high-ceev switching thiab txiav tawm. Kev hloov pauv ntawm cov tam sim no ncaj qha mus rau hauv high-frequency alternating tam sim no los hloov lub converter los tsim qhov yuav tsum tau muaj ib lossis ntau pawg ntawm voltages! Yog vim li cas rau kev hloov mus rau high-frequency alternating tam sim no yog qhov ua tau zoo ntawm high-frequency alternating tam sim no nyob rau hauv lub transformer Circuit Court yog siab tshaj li ntawm lub lag luam hwj chim 50Hz los yog 60Hz. Yog li ntawd, lub zog hloov hluav taws xob hloov pauv tuaj yeem ua rau me me, thiab nws tsis kub heev thaum lub zog hloov hluav taws xob ua haujlwm, thiab cov khoom lag luam tus nqi qis dua lub zog zaus DC tswj fais fab mov. Yog tias koj tsis hloov 50Hz lossis 60Hz rau hauv siab zaus, ces kev hloov hluav taws xob tsis ua rau muaj kev nkag siab. Lub zog hloov hluav taws xob tuaj yeem muab faib ua ob hom: cais thiab tsis cais. Hom kev sib cais yuav tsum muaj lub tshuab hluav taws xob hloov hluav taws xob, thiab lub zog hluav taws xob sib cais tsis tas yuav tsum tau cais tawm. Piv nrog rau cov khoom siv hluav taws xob DC ib txwm muaj, lub zog hloov hluav taws xob muaj qhov zoo ntawm qhov me me, lub teeb yuag, thiab kev ua haujlwm siab.
