Fais fab mov - nws ntau ntau yam thiab cov kev siv

Ib tug ntawm cov ntsiab teeb meem kev nyuaj siab los ntawm ob leeg tej thiab novice enthusiasts tsim ntawm hluav taws xob thiab xov tooj cua kiag li lawm, yog lub hwj chim. Rau cov kev xav tau ntawm cov ntaub ntawv thiab tsim ib tug ntaus ntawv xws li ib lub hwj chim qhov twg los (SP).

Thaum xaiv xws li ib tug ntaus ntawv yuav tsum coj mus rau hauv tus account ib tug xov tooj ntawm qhov tseem ceeb yam, uas yog txiav txim los ntawm kev khiav hauj lwm tej yam kev mob, kev ruaj ntseg uas yuav tsum tau, lub zog thiab loads ntawm lwm yam uas. Ntxiv mus, qhov yuav tsum tau coj mus rau hauv tus account lub hom xws li, xws li cov mains mov - nws yuav ua tau ib tug haib, medium hwj chim los sis micropower.

Thawj thiab foremost koj xav tau them sai sai mus raws li qhov tsis muaj tus ntaus ntawv yuav tsum tau ntawm cov powered ntaus ntawv. Lub hwj chim mov muaj ib tug tej yam muaj pes tsawg tus ntawm zoo xws li cov yam ntxwv npaj: noj tam sim no, voltage, zog yuav tsum tau (qub los yog nominal) theem mus rau stabilize qhov voltage, pub (thiab nws yam tsawg kawg nkaus thiab nyiaj pab ntau tshaj tus nqi), cov theem ntawm voltage ripple.

Tsis tas li ntawd, lub hwj huam mov muaj ib co ntawm cov qualities thiab cov yam ntxwv uas ncaj qha kev cuam tshuam rau nws cov lag luam thiab tau. Piv txwv li, lub muaj los yog tsis tuaj kawm ntawv ntawm kev tiv thaiv, qhov nyhav thiab qhov ntev ntawm lub ntaus ntawv.

Fais fab mov - ib feem ntawm tej hluav taws xob ntaus ntawv. Txhais tau hais tias ob qho tag nrho thawj thiab fais fab mov yuav tsum tsim nyog kiag li ua raws li qhov yuav tsum tau kev uas thov nyob rau hauv general rau cov khoom thiab nws tivthaiv qhov chaw. Yog hais tias xws li ib tug ntaus ntawv raws li ib lub hwj chim qhov twg los, ib co kev xaiv yuav tuaj tsis pub dhau ntau yam, nws muaj peev xwm ua rau disharmony nyob rau hauv cov khoom thiab nws puas tsuaj.

Muaj ntau ntau views ntawm network zog qhov chaw:

- nrog rau cov condenser, los yog damping resistor (thiaj li hu ua transformerless);

- linear, uas yog cov txheej txheem ntawm raws li lub classical tswvyim (transformator- rectifier, ua raws li los ntawm pom thiab stabilization);

- high-voltage thiab high-zaus mem tes;

- theem nrab mem tes (transformer Circuit Court khiav hauj lwm rau siab frequencies Lim - converter);

- sawv-nyob ib leeg fais fab mov;

- linear Fe.

Tawm yog lub feem ntau yooj yim thiab pheej yig rau hobbyists. Lawv feem ntau siv nyob rau hauv me me-sized pab kiag li lawm, xws li chargers, roj teeb, lub hwj chim mov systems, signaling, thiab hais txog. Tsis tas li ntawd no yuav tsum tau ntaus nqi rau qhov uas uninterrupted fais fab mov (UPS).

Txawm li cas los, thaum uas siv cov tam sim no qhov tseem ceeb ntawm ntau tshaj ib ampere, cov hauj lwm zoo ntawm xws li ib tug ntaus ntawv, raws li ib tug linear fais fab mov yog sharply txo los ntawm ib tug ntau yam yog vim li cas:

- stabilization tau yuav ua tsis ruaj tsis khov vim oscillations ntawm cov mains voltage;

- siab currents yuav tsum tau lub installation ntawm loj heatsinks rau regulating transistors thiab daws kom tiav diode;

- nyob rau stabilizer tswv yim yuav tsum noj ntau kom meej meej dua voltage tshaj tej siv tau nrog hloov mus hloov los nyob rau hauv lub network.

Tsis ntev los no, txawm li cas los, nws tau ua heev mem tes converters (secondary), raws li zoo raws li ib lub hwj chim qhov twg los rau lub hauv paus ntawm high-zaus transducers nrog transformerless inputs.
