Hais txog kev tsim cov lim thiab voltage stabilizing Circuit Court
1. Ntaus thiab lim kev xaiv Circuit Court
Capacitors, inductors, RC circuits, thiab lwm yam lim circuits feem ntau siv nyob rau hauv rectifier lim circuits. Los ntawm kev tsim lub txee electromotive quab yuam rau cov pulsing tam sim no nrog ib qho inductor, ib tus tuaj yeem ua tiav inductor filtering, uas tiv thaiv kev hloov pauv tam sim no. Cov nyhuv lim dej txhim kho nrog nce inductance. Cov chaw nres tsheb nrog cov khoom thauj siab tam sim no thiab tsis xav tau kev pom feem ntau siv nws. Lub lim lim hu ua RC lim Circuit Court yog siv los txuas cov capacitors thiab resistors. Txo ib feem ntawm DC voltage, ib tug resistor tsuas yog tsim nyog rau circuits uas tsis tshua muaj tam sim no.Capacitive filtering nce lub voltage amplitude thiab stabilizes lub rectified tso zis voltage los ntawm kev siv lub capacitor tus nqi thiab tawm los. Nws ua haujlwm zoo nyob rau hauv ntau yam rectifier circuits thiab muaj cov nyhuv lim dej zoo. Hom, muaj peev xwm, thiab tiv taus tus nqi hluav taws xob ntawm lim capacitors yog thawj yam uas yuav tsum tau xav txog thaum xaiv ib qho.
Tantalum electrolytic, aluminium electrolytic, thiab monolithic capacitors yog cov piv txwv ntawm nquag siv rectifier thiab lim capacitors. Txawm hais tias muaj lub peev xwm loj, aluminium electrolytic capacitors muaj qhov tsis tshua muaj hluav taws xob, muaj qhov xau loj tam sim no, thiab kev ua haujlwm qis (txog 70 degree). Tantalum capacitors feem ntau yog siv nyob rau hauv cov chaw uas yuav tsum tau ntau dua vim hais tias lawv muaj siab dua voltages, siab ua hauj lwm kub, thiab tsawg to tam sim no tshaj txhuas electrolytic capacitor. Loj insulating tsis kam, tsis tshua muaj peev xwm, compact peev xwm, tsis tshua muaj kev khiav hauj lwm kub (txog 55 degree), thiab siab withstand voltage yog tag nrho cov yam ntxwv ntawm polyester capacitors. Qhov loj me, siab tiv taus voltage, ruaj khov tshuaj thiab thermal yam ntxwv, thiab lub peev xwm me me tuaj yeem ua tiav siv monolithic capacitors.
Feem ntau, thaum lub rectified tso zis tam sim no loj, qhov voltage yuav tsum stabilized los ntawm electrolytic capacitor filtering. Thaum cov zis tam sim no me me, cov capacitors zoo tib yam lossis electrolytic capacitors tuaj yeem siv rau lim. Yog hais tias muaj ripple coefficient yuav tsum tau rau cov zis voltage ntawm DC stabilized fais fab mov los yog kom tsis txhob muaj lub suab nrov, nws yog qhov zoo tshaj plaws los siv electrolytic capacitors thiab me me-capacity tsis-polar capacitors nyob rau hauv parallel: me me-capacity capacitors tuaj yeem lim tawm siab. -order harmonics nyob rau hauv pulsating DC, thiab electrolytic capacitors Nws muaj peev xwm lim tawm ib tug loj npaum li cas ntawm tsawg zaus Cheebtsam, muaj ib tug dav voltage stabilizing ntau yam, thiab muaj cov teebmeem zoo. Lub rectifier lim Circuit Court tsis tas yuav muaj peev xwm ntau dhau thiab qhov hluav taws xob tsis kam. Feem ntau, lub capacitance ntawm lub capacitor yog kwv yees raws li cov zis tam sim no. Yog tias cov zis tam sim no loj, lub peev xwm kuj loj. Yog tias qhov tam sim no me me, lub peev xwm kuj me me. Txawm li cas los xij, lub peev xwm loj dhau lawm yuav txo qhov tso zis voltage tus nqi, thaum me me dhau ntawm lub capacitance yuav ua rau qhov loj thiab tsis ruaj khov voltage hloov. Lub peev xwm raug txiav txim siab. Tus nqi hluav taws xob tiv thaiv feem ntau yog 1.5 mus rau 2 npaug ntawm qhov ua haujlwm voltage ntawm lub voj voog txuas.
2. Voltage stabilizing Circuit Court thiab xaiv cov khoom siv
Muaj ob hom voltage stabilizing circuits: discrete tivthaiv voltage stabilizing circuits thiab integrated voltage stabilizing circuits. Lub invention yog tsuas yog siv nyob rau hauv tsawg-voltage thiab me-tam sim no rectifier circuits, thiab muaj cov yam ntxwv ntawm me me, yooj yim Circuit Court, high voltage stabilization raug, thiab yooj yim siv thiab debugging. Thaum xaiv, koj thawj zaug yuav tsum tau txiav txim siab seb cov koob yog qhov zoo lossis qhov tsis zoo, kho tau lossis kho, thiab qhov thib ob, koj yuav tsum xaiv cov qauv tshwj xeeb raws li nws qhov ntsuas voltage thiab tam sim no. Nyob rau tib lub sijhawm, thaum lub ntsuas hluav taws xob txuas nrog lub ntsuas hluav taws xob, qee qhov kev tiv thaiv yuav tsum tau ntxiv kom tsim nyog, xws li txuas diodes ntawm cov tswv yim / tso zis terminals los tiv thaiv luv luv Circuit Court ntawm input terminals, thiab txuas me me capacitors ntawm cov tswv yim. terminals thiab hauv av los txwv cov input voltage amplitude, thiab lwm yam.
