Txoj cai ntawm high-frequency fais fab mov
Main Circuit Court
Tag nrho cov txheej txheem ntawm kev tawm tswv yim thiab cov khoom siv tawm los ntawm AC lub zog hluav taws xob, suav nrog: 1. Cov tswv yim lim: Nws txoj haujlwm yog los lim tawm cov clutter uas twb muaj lawm hauv daim phiaj fais fab, thaum tseem cuam tshuam cov lus tawm tswv yim ntawm cov khoom tsim tawm rau hauv daim phiaj hluav taws xob pej xeem. 2. Rectification thiab filtering: ncaj qha rectifying AC ntawm daim phiaj fais fab mus rau smoother DC fais fab mov rau qib tom ntej ntawm kev hloov. 3. Inversion: Transforming rectified direct tam sim no mus rau high-frequency alternating tam sim no, uas yog ib feem ntawm high-frequency. Qhov ntau zaus, qhov sib piv me me ntawm ntim, qhov hnyav, thiab cov zis hluav taws xob. 4. Tso zis rectification thiab filtering: Muab ruaj khov thiab txhim khu kev qha DC fais fab mov raws li qhov yuav tsum tau ua.
tswj Circuit Court
Ntawm ib sab, cov qauv raug coj los ntawm qhov kawg tso zis, piv nrog cov txheej txheem teeb tsa, thiab tom qab ntawd lub inverter yog tswj los hloov nws cov zaus lossis mem tes dav kom ua tiav cov zis ruaj khov. Ntawm qhov tod tes, raws li cov ntaub ntawv muab los ntawm kev ntsuas Circuit Court thiab txheeb xyuas los ntawm kev tiv thaiv Circuit Court, tswj Circuit Court yog muab los muab ntau yam kev tiv thaiv rau tag nrho lub tshuab.
Kev kuaj xyuas Circuit Court
Ntxiv nrog rau kev muab ntau yam kev khiav hauj lwm tsis nyob rau hauv kev tiv thaiv Circuit Court, ntau yam khoom siv ntsuas cov ntaub ntawv kuj tau muab.
Pab txhawb zog
Muab cov khoom siv hluav taws xob sib txawv rau txhua lub voj voog ib leeg. Lub hauv paus ntsiab lus ntawm kev tswj hluav taws xob hloov hluav taws xob hloov pauv hloov K yog rov qhib thiab tawm ntawm lub sijhawm tshwj xeeb Spaced repetition. Thaum hloov K yog qhib, input fais fab E yog muab los thauj RL los ntawm kev hloov K thiab lim circuit. Thaum lub sijhawm hloov pauv tag nrho, lub zog E muab lub zog rau kev thauj khoom; Thaum hloov K raug rho tawm, lub zog tawm tswv yim E cuam tshuam cov khoom siv hluav taws xob. Nws tuaj yeem pom tau tias cov khoom siv hluav taws xob muab hluav taws xob muab lub zog rau kev thauj khoom tsis tu ncua. Txhawm rau kom cov khoom thauj tau txais cov khoom siv hluav taws xob tas mus li, qhov hloov hluav taws xob tswj hluav taws xob yuav tsum muaj cov khoom siv hluav taws xob uas khaws cia ib feem ntawm lub zog thaum lub qhov hloov pauv tau qhib, thiab tso tawm mus rau qhov chaw thau khoom thaum lub tshuab hluav taws xob kaw. Nyob rau hauv daim duab, lub Circuit Court tsim ntawm inductor L, capacitor C2, thiab diode D muaj cov haujlwm no. Inductance L yog siv los khaws lub zog. Thaum lub tshuab hluav taws xob raug txiav, lub zog khaws cia hauv inductance L raug tso tawm mus rau lub load los ntawm diode D, kom lub load tuaj yeem tau txais lub zog tas li thiab ruaj khov. Vim tias diode D ua rau cov load tam sim no tsis tu ncua, nws hu ua Flyback diode. Qhov nruab nrab qhov hluav taws xob EAB nruab nrab ntawm AB tuaj yeem sawv cev los ntawm qhov sib npaug hauv qab no: EAB=TON / T * E, qhov twg TON yog lub sijhawm txhua qhov hloov pauv, thiab T yog lub voj voog ua haujlwm ntawm qhov hloov mus rau / tawm ( piv txwv li qhov suav ntawm qhov hloov ntawm lub sijhawm TON thiab lub sijhawm tawm TOFF). Los ntawm qhov sib npaug, nws tuaj yeem pom tau tias kev hloov pauv hloov ntawm lub sijhawm thiab lub voj voog ua haujlwm kuj hloov qhov nruab nrab voltage ntawm AB. Yog li ntawd, cia li kho qhov piv ntawm TON thiab T nrog cov kev hloov hauv load thiab input fais fab voltage tuaj yeem tswj cov zis voltage V0 tsis hloov. Hloov lub sij hawm TON thiab lub luag hauj lwm voj voog piv, tseem hu ua hloov lub luag hauj lwm voj voog ntawm lub mem tes, yog ib txoj kev hu ua "Time Ratio Control" (TRC).
