AMC1200SDUBR 100% E Ncha & Ea Pele ea ho Isolla Amplifier 1 Phapang ea Potoloho 8-SOP

Ho na le mekhoa e meraro ea moralo e sebelisetsoang li-amplifiers tsa ho itšehla thajana, ho kenyelletsa:

1. Ho itšehla thajana ho Transformer

Mofuta ona oa ho itšehla thajana o sebelisa matšoao a PWM kapa a feto-fetohang khafetsa.Ka hare, amplifier e kenyelletsa oscillator ea 20 KHz, rectifier, filter, le transformer ho matlafatsa mohato o mong le o mong oa ho itšehla thajana.

1).Rectifier e sebelisoa e le ho kenya letsoho ho amplifier ea mantlha ea ts'ebetso.

2).Hokela transformer ho phepelo ea motlakase.

3).Oscillator e sebelisoa e le kenyelletso ea amplifier ea bobeli ea ts'ebetso.

4) .LPF e sebelisoa ho tlosa likarolo tsa maqhubu a mang.

5).Melemo ea ho itšehla thajana ea transformer haholo-holo e kenyelletsa CMRR e phahameng, linearity le ho nepahala.

Likopo tsa ho itšehla thajana li kenyelletsatsa bongaka, nuclearle lisebelisoa tsa indasteri.

2. Optical ho itšehla thajana

Ka ho itšehla thajana, lets'oao la l le ka fetoloa ho tloha ho lets'oao la baeloji ho ea ho lets'oao la optical ke LED bakeng sa ts'ebetso e tsoelang pele.Tabeng ena, potoloho ea mokuli ke potoloho ea ho kenya letsoho, ha potoloho e hlahisoang e ka thehoa ho tloha phototransistor.Li-circuits tsena li tsamaisoa ke libeteri.Potoloho ea i/p e fetola lets'oao hore e be leseli, 'me potoloho ea o/p e fetola leseli hore e be lets'oao.

Melemo ea optical isolation e kenyelletsa:

1).Ka ho e sebelisa, re ka fumana amplitude le maqhubu a tala.

2).E hokahane ka optically ntle le modulator kapa demodulator.

3).E ntlafatsa polokeho ea mokuli.

Likopo tsa ho itšehla thajana li kenyelletsa taolo ea ts'ebetso ea indasteri, ho nkuoa ha data, tekanyo ea biomedical, tlhahlobo ea mokuli, likarolo tsa sebopeho, lisebelisoa tsa liteko, taolo ea SCR, jj.

3. Ho itšehla thajana ka capacitor

1).E sebelisa frequency modulation le encoding ea digital ea motlakase oa ho kenya.

2)Motlakase oa ho kenya o ka fetoloa ho tefiso e lekanyelitsoeng ho switching capacitor.

3).E kenyelletsa li-circuits tse kang modulator le demodulator.

4).Lipontšo li romeloa ka lithibelo tse fapaneng tsa capacitive.

5).Bakeng sa mahlakore ka bobeli, fana ka ka thoko.

Melemo ea ho itšehla thajana ea capacitive e kenyelletsa:

1).Ho itšehla thajana hona ho ka sebelisoa ho felisa lerata la ripple

2)Tsena li sebelisetsoa ho etsisa tsamaiso

3).E kenyelletsa linearity le phaello e phahameng ea botsitso.

4).E na le tšireletso e phahameng ho lerata la makenete

5).Ka ho e sebelisa, u ka qoba lerata.

Likopo tsa ho itšehla thajana li kenyelletsa ho fumana data, likarolo tsa sebopeho, ho beha leihlo mokuli, electroencephalography, le electrocardiogram.
