Qhov kub xws li nyob rau hauv cov kev tswj circuits

Tsis Siv Neeg tswj systems tsim los tswj tshaj tsis xws li tam sim no, voltage, lub hwj chim, siab thiab lwm yam Ib tug tshwj xeeb qhov chaw nyob rau hauv no hom ntawm system yog muab tswj schemes. Nyob ntawm seb tus kwv, siv ib tug los yog lwm yam kev tswj hauv paus ntsiab lus. Yog hais tias peb xav nyob rau hauv cov cua kub hais, ces qhov no nyob rau hauv feem ntau daim ntaub ntawv yog tsis muaj yuav tsum tau tsim kom muaj ib tug high-ceev Circuit Court. Qhov no simplifies Circuit Court siv ntawm tus dais, thiab, tseem ceeb tshaj, tso cai rau koj siv "maj" hom rau lub hwj chim modules. Qhov no mus kom ze ho ncua roj teeb lub neej thiab thiaj li downtime thaum kho khoom siv. Nyob rau hauv ib tug ntau lawm puag ncig nws yog - ib qho tseem ceeb. Txhua yam tsis tau xav nres cov kab ntau lawm ua rau ib tug txo nyob rau hauv qhov kev tso tawm ntawm qhov kawg khoom, uas, ntawm chav kawm, thaws rov los nyob rau hauv nws cov nqi.

Raws li ib qho piv txwv, xav txog ib tug me me system nyob qhov twg qhov kub thiab txias xws li yog siv. Tus tswj system muaj ob inputs - reference thiab tawm tswv yim Pib ntsais koj teeb. Xav hais tias cov teeb liab yuav tsum tau mus coj cov parameter hauj lwm mus rau ib tug tej yam muaj nuj nqis. Raws li siv kub xws li maj mam tsub kom tus tam sim no nyob rau hauv cov cua kub hais rau cov nyiaj pab ntau tshaj. Tom qab ntawd yuav piv lub tswv yim teeb liab thiab cov kev siv. Thaum lawv ntes tau - yuav smooth tawm tus kwv. Feem ntau nyob rau hauv xws tshuab rau kom rov qab hysteresis pw rau / tawm - qhov no yog tsim nyog los xyuas kom meej ruaj khov lag luam ntawm lub tag nrho qhov system.

Yav tas los, rau switching lub ntsiab Circuit Court hu cua sov siv circuits muaj ib tug xov tooj ntawm disadvantages: ib tug ntse nce nyob rau hauv load tam sim no, sai coj ntawm cov neeg, thiab lwm yam Niaj hnub nimno kub xws li lwm yam uas lub hwj chim modules raws li thyristors, triacs, IGBT-transistors, etc. Txhua chav tsev nws muaj nws tus yam ntxwv nyob rau hauv cov kev tswj ntawm ntawd thiab yuav tsum muab xav thaum tsim lub ntaus ntawv.

Zoo zeem muag kev tswj haib cov chaw ntau lawm, piv txwv li, induction rauv taws nte, ib tug thyristor kub xws li. Lub caij muaj kev kawm zoo heev, thiab nws ua zoo thaum lub sij hawm kev lag luam nrog ib tug resistive load. Nyob rau hauv cov kev tswj ntawm lwm yam loads, cov tshiab li ntawm ib lub sij hawm yog maj yielding nws txoj haujlwm ntau niaj hnub schemes.

Tej zaum nws yog tsim nyog los siv ib tug kub regulator. Ib tug piv txwv zoo nyob rau hauv cov ntaub ntawv no yuav pab tau raws li ib tug me me ntaus ntawv uas ua hauj lwm nyob rau hauv lub sauna. Raws li koj tau pom, muaj yog ib tug siv lub teeb liab (nyob rau hauv degrees Celsius). Tswv yim nyob rau hauv cov ntaub ntawv no yog lub teeb liab los ntawm ib tug kub sensor uas yog pov tseg rau hauv lub sauna. Txoj ntsiab cai tib tej hauj lwm thiab cov dej kub xws li, hloov xwb lub hom sensor siv. Xws li no kuj siv nyob rau hauv qhuav (ntawm chav kawm, lawv muaj ib tug loj npaum li cas muaj peev xwm).

Nrog lub advent ntawm lub hwj chim lub Cheebtsam raws li semiconductor pab kiag li lawm yog ib tug gradual hloov ntawm "laus" schemes. Nyob twj ywm unchanged tsuas tswj lub hauv paus ntsiab lus nyob rau hauv uas cov pab kiag li lawm ua hauj lwm.
