Yuav ua li cas cov oscilloscopes ntsuas qhov poob ntawm kev hloov fais fab mov fais fab
Nrog rau kev xav tau loj zuj zus rau kev hloov cov khoom siv hluav taws xob hauv ntau qhov kev lag luam, ntsuas thiab tshuaj xyuas lub zog poob ntawm cov tiam tom ntej hloov cov khoom siv hluav taws xob yog qhov tseem ceeb tshaj plaws. Hauv cheeb tsam daim ntawv thov no, TDS5000 lossis TDS7000 series digital fluorescence oscilloscopes, ua ke nrog TDSPWR2 lub zog ntsuas software, tuaj yeem pab koj ua kom tiav cov kev ntsuas thiab kev tshuaj xyuas tau yooj yim.
Kev hloov pauv hom hluav taws xob tshiab (SMPS: Hloov Hom PowerSupply) architecture, yuav tsum muaj cov ntaub ntawv siab ceev thiab GHz-chav kawm processors los muab cov khoom siv hluav taws xob tam sim no thiab tsis tshua muaj hluav taws xob, uas muab cov khoom siv hluav taws xob tsim hluav taws xob hauv kev ua haujlwm, lub zog ceev, kev ntseeg siab thiab tus nqi ntawm ntau yam, ntxiv qhov tsis pom kev tshiab siab. Txhawm rau coj cov kev xav tau no mus rau hauv tus account hauv kev tsim, cov neeg tsim qauv tau txais cov qauv tshiab xws li kev hloov kho synchronous, kev kho lub zog lim dej thiab nce kev hloov pauv ntau zaus. Cov thev naus laus zis no tseem coj tau qee qhov kev sib tw siab dua, xws li kev poob hluav taws xob ntau dua ntawm kev hloov khoom siv, thermal dissipation thiab ntau dhau EMI / EMC.
Los ntawm "off" (on) mus rau "on" (tawm) lub xeev ntawm lub sijhawm hloov pauv, cov khoom siv hluav taws xob yuav tshwm sim lub zog poob siab. (Kev hloov khoom siv hauv lub xeev "on" lossis "tawm" muaj qhov poob qis dua vim tias qhov tam sim no los ntawm lub cuab yeej lossis qhov hluav taws xob thoob plaws lub cuab yeej me me). Inductors thiab transformers cais cov zis voltage thiab smooth lub load tam sim no. Inductors thiab transformers kuj tseem raug hloov pauv ntau zaus, uas tuaj yeem ua rau lub zog tawg thiab qee zaus tsis ua haujlwm vim qhov saturation.
Txij li thaum lub hwj chim dissipated nyob rau hauv lub switching fais fab mov chav tsev txiav txim siab tag nrho cov efficiency ntawm lub thermal nyhuv ntawm lub hwj chim mov, kev txiav txim ntawm lub hwj chim poob nyob rau hauv lub switching unit thiab inductor / transformer yog ib qho tseem ceeb heev ntsuas. Qhov ntsuas no txiav txim siab lub zog efficiency thiab thermal dissipation.
