Aperiodic cais fais fab adapter
Tam sim no, feem ntau ntawm cov khoom siv fais fab, txawm tias nws tus kheej zoo siab lossis lwm yam zoo siab, yog qhov hluav taws xob ruaj khov circuits tswj los ntawm PWM system. Nyob rau hauv hom fais fab adapter no, lub hwj chim adapter yog ib txwm nyob rau / tawm ib ntus, thiab PWM system tsuas yog hloov cov mem tes dav ntawm txhua lub voj voog. Vim tias PWM system ua haujlwm nyob rau hauv cheeb tsam linear, nws yuav tsis saturate los yog txiav tawm: nws yuav tsis ua rau lub mem tes dav ntawm ib tug tej yam voj voog zero, los yog poob tswj thiab mus rau lub siab tshaj plaws mem tes dav ib txwm teem los ntawm lub intermittent oscillator. Yog li ntawd, nws tuaj yeem hais tias qhov kev tswj hwm zoo li no tsis tu ncua, tsuas yog hloov "ntau" tab sis tsis yog "zoo".
Sib txawv ntawm aperiodic fais fab adapter, nws cov txheej txheem tswj pulse tsis hloov pauv tsis tu ncua, tab sis tsuas yog ob lub xeev: thaum cov zis hluav taws xob ntawm lub hwj chim adapter tshaj qhov ntsuas tus nqi, tus mem tes tswj saturates thiab tig rau, thiab lub hwj chim adapter nres kev co; Thaum cov zis hluav taws xob qis dua qhov ntsuas tus nqi, lub tshuab hluav taws xob pulse kaw, thiab lub hwj chim adapter pib oscillate. Yog li ntawd, lub pulse maub los tsuas muaj ob lub xeev ntawm "O" thiab "1", thiab nws cov oscillation yog discontinuous thiab aperiodic, thaum lub sij hawm piv ntawm lub hwj chim adapter ntawm "U" thiab "cog" nyob ntawm qhov load loj. Thaum lub load tam sim no txo, qhov tso zis voltage yuav tsis txo sai heev vim lub ncua sij hawm tawm ntawm lub lim capacitor, thiab lub hwj chim adapter yuav nyob rau hauv lub txiav-tawm lub xeev kom txog rau thaum cov zis voltage poob qis dua tus nqi ntsuas, thiab ces lub hwj chim. adapter yuav rov qhib dua. Lub sij hawm txiav tawm ntawm lub hwj chim adapter nyob ntawm qhov load tam sim no. Lub rau / tawm ntawm lub hwj chim adapter tsis yog tswj los ntawm PWM system, tab sis los ntawm cov khoom siv hluav taws xob hloov pauv los ntawm cov zis hluav taws xob. Yog li ntawd, hom aperiodic fais fab adapter no zoo heev rau lub hwj chim mov nrog tsis tu ncua load los yog loj load hloov.
Thaum pib ntawm txoj kev loj hlob ntawm aperiodic fais fab adapter, lub Circuit Court qauv ntawm lwm yam excitation yog saws. Lub tshuab hluav taws xob sib piv uas tsim los ntawm kev ua haujlwm amplifier hloov cov zis voltage sampling rau hauv qib tswj kom tswj cov zis mem tes ntawm lwm yam excitation oscillator. Thaum cov zis hluav taws xob tswj hwm qhov ntsuas hluav taws xob, tus sib piv tso tawm cov hluav taws xob siab, thiab oscillator tig tawm cov zis mem tes kom txiav tawm lub hwj chim adapter. Thaum cov zis hluav taws xob txo qis, tus sib piv tso tawm cov hluav taws xob tsawg, thiab cov oscillation pulse tig rau lub hwj chim adapter. Txhawm rau ua kom yooj yim rau hauv Circuit Court, feem ntau ntawm aperiodic fais fab adapters txais yuav tus kheej zoo siab oscillation hom thiab ncaj qha siv cov regulator raws li cov hluav taws xob hloov. Vim tias nws cov txheej txheem tswj hwm yog kev sib xyaw ua ke ntawm lub sijhawm sib npaug ntawm lub xeev oscillation thiab lub xeev kev tawm tsam (los yog lub xeev thaiv), nws yog hu ua oscillation suppression type converter, namely, ringingholdeconverter, uas yog hu ua RCC hom hloov regulator. Qhov txawv txav hauv Circuit Court yog tias PWM lub hwj chim adapter muaj ib qho kev ywj pheej sampling yuam kev amplifier thiab DC amplifier los tsim ib tug mem tes dav modulation system, thaum lub RCC fais fab mov tsuas yog muaj ib tug regulator los tsim ib tug hluav taws xob hloov mus rau lub hwj chim tswj. / tawm ntawm lub hwj chim adapter.
