Hloov hom fais fab mov thiab lub luag hauj lwm ntawm high zaus transformers
Hloov transformer nrog nws cov kev hloov pauv siab, me me, lub teeb yuag thiab ua haujlwm nyob rau hauv ntau qhov sib txawv ntawm qhov voltages thiab ntau lwm yam zoo, hauv lub xov tooj ntawm tes charger, roj teeb tsheb charger thiab ntau yam khoom siv hauv tsev yuav siv rau hauv kev hloov hluav taws xob, ces nyob rau hauv lub switching fais fab mov peb yuav nco ntsoov pom tias muaj ib tug high-frequency transformer, hnub no peb yuav tham txog no high-frequency transformer los tham txog nws lub luag hauj lwm nyob rau hauv lub switching fais fab mov.
Switching power supply txoj cai ntawm kev ua haujlwm
Peb paub tias qhov hloov hluav taws xob hloov hluav taws xob muaj tus kheej zoo siab hloov hluav taws xob hloov hluav taws xob thiab nws lub zog hloov hluav taws xob muaj ob pawg, thiab tam sim no peb muaj nws lub zog hloov hluav taws xob ua piv txwv los piav qhia nws cov txheej txheem ua haujlwm, kom peb tuaj yeem piav qhia ntxiv txog lub luag haujlwm. ntawm high-frequency transformer nyob rau hauv lub switching fais fab mov. Nyob rau hauv nws excitation switching fais fab mov los ntawm ib tug ywj siab oscillator los tsim kev tswj mem tes teeb liab los tswj lub switching tube rau thiab tawm, thaum lub switching tube V nyob rau hauv lub switching xeev, ces nyob rau hauv lub high-frequency transformer ntawm thawj winding yuav muaj hluav taws xob. muaj peev xwm, yog li ntawd nws yuav raug ntxias mus rau theem nrab winding, qhov thib ob winding ua lub peev xwm hluav taws xob los ntawm VD2 diode ntawm electrolytic capacitors yuav tsum tau them, cov electrolytic capacitors ua si lub lim dej, kom nws yuav tos kom ruaj khov DC. voltage ntawm load RL.
Hloov fais fab mov siv nyob rau hauv lub luag hauj lwm ntawm high-frequency transformers
Kuv xav tias nyob rau hauv lub high-frequency transformer nyob rau hauv lub switching fais fab mov muaj ob lub luag hauj lwm tseem ceeb, cov nram qab no peb hais raws. Thawj qhov taw tes yog tias kev siv cov tshuab hluav taws xob ntau zaus hauv kev hloov cov khoom siv hluav taws xob yog txhawm rau txhim kho kev hloov pauv ntawm lub zog hluav taws xob. Raws li cov high-frequency transformer hlau core yog siv nyob rau hauv silicon steel sheet core, silicon steel ntawv conductivity yog zoo heev, muaj peev xwm zoo heev txhim kho lub resistivity thiab permeability, yog li kev txhim kho lub conversion efficiency ntawm switching fais fab mov, nce nws cov zis zog.
Lub ntsiab lus thib ob yog los tiv thaiv lub nraub qaum ntawm cov khoom thauj thiab kev nyab xeeb ntawm tus kheej, ua lub luag haujlwm hauv kev sib cais kev nyab xeeb, tab sis kuj ua kom huv lub zog hluav taws xob los tiv thaiv kev cuam tshuam. Peb xav tias qhov hloov hluav taws xob hloov pauv hauv kev ua haujlwm vim qee qhov tshwm sim los ntawm qhov tso zis hluav taws xob ntau dhau, yog li cov hluav taws xob siab yuav raug xa mus rau qhov kev tiv thaiv Circuit Court, ces qhov hloov hluav taws xob hauv kev tiv thaiv Circuit Court yog qhib los tiv thaiv lub hom, nws yuav "txiav" lub raj hloov kom tsis txhob ua haujlwm, tab sis lub raj hloov pauv tsis ua haujlwm, lub tshuab hluav taws xob ntau zaus thaum kawg ntawm thawj zaug tsis muaj txoj hauv kev! Tsim hluav taws xob muaj peev xwm, thiaj li hais tias qhov thib ob winding ntawm high-frequency transformer tsis tuaj yeem tau txais qhov induction ntawm hluav taws xob muaj peev xwm, qhov tso zis sab ntawm qhov hluav taws xob tso tawm, yog li tiv thaiv lub load los ntawm high-voltage puas. Yog hais tias koj tsis siv high-frequency transformer ib zaug qhov tshwm sim no yuav txaus ntshai heev, yog hais tias lub switching tube yog punctured, high voltage tso zis ncaj qha rau ntawm cov khoom siv hluav taws xob, hluav taws xob hluav taws xob hluav taws xob ncaj qha, thiab txawm muaj kev nyab xeeb ntawm tib neeg lub neej.
