I-AMC1200SDUBR 100% Isikhulisi Esisha Nokwangempela Sokuzihlukanisa 1 Umehluko Wesekethe 8-SOP

Kunezindlela ezintathu zokuklama ezisetshenziselwa i-isolation amplifiers, okuhlanganisa:

1. Ukuhlukaniswa kwe-Transformer

Lolu hlobo lokuzihlukanisa lusebenzisa i-PWM noma amasiginali ashintshwayo.Ngaphakathi, i-amplifier ifaka i-oscillator engu-20 KHz, isihlungi, isihlungi, kanye nesiguquli ukuze kunikwe amandla isigaba ngasinye sokuhlukaniswa.

1).I-rectifier isetshenziswa njengokufaka ku-amplifier eyinhloko yokusebenza.

2).Xhuma i-transformer kugesi.

3).I-oscillator isetshenziswa njengokufakwa kwe-amplifier yesibili yokusebenza.

4).I-LPF isetshenziselwa ukususa izingxenye zamanye amafrikhwensi.

5).Izinzuzo zokuhlukaniswa kwe-transformer ikakhulukazi zifaka i-CMRR ephezulu, umugqa kanye nokunemba.

Izicelo zokuhlukaniswa kwe-transformer zibandakanyaezokwelapha, zenuzikanye nezicelo zezimboni.

2. Ukuhlukaniswa kwamehlo

Kulokhu kuhlukaniswa, isignali engu-l ingashintshwa isuke kusiginali yebhayoloji iye kusignali yokubona nge-LED ukuze iqhubeke nokusebenza.Kulesi simo, isifunda sesiguli siyisifunda sokufaka, kuyilapho isifunda sokukhipha singakhiwa kusuka ku-phototransistor.Lawa masekhethi anikwa amandla amabhethri.Isekhethi ye-i/p iguqula isignali ibe ukukhanya, futhi isekethe ye-o/p iguqule ukukhanya kubuyisele isignali.

Izinzuzo zokuhlukaniswa kwe-optical zifaka:

1).Ngokuyisebenzisa, singathola i-amplitude nemvamisa eluhlaza.

2).Ixhumeke ngokubonakalayo ngaphandle kwemoduli noma idemodulator.

3).Ithuthukisa ukuphepha kwesiguli.

Izicelo zokuhlukaniswa kwe-transformer zifaka phakathi ukulawulwa kwenqubo yezimboni, ukutholwa kwedatha, ukulinganisa kwe-biomedical, ukuqapha kwesiguli, izingxenye zesixhumi esibonakalayo, okokusebenza kokuhlola, ukulawula kwe-SCR, njll.

3. Ukuhlukaniswa kwe-capacitor

1).Isebenzisa i-frequency modulation kanye ne-digital encoding ye-voltage yokufaka.

2)I-voltage yokufaka ingashintshwa ibe yinani elihlobene ne-switching capacitor.

3）.Kuhlanganisa amasekhethi afana nemoduli nedemodulator.

4)Amasignali athunyelwa ngezithiyo ze-capacitive ezihlukene.

5)Kuzo zombili izinhlangothi, hlinzeka ngokuhlukene.

Izinzuzo ze-capacitive isolation zifaka:

1).Lokhu kuhlukaniswa kungasetshenziswa ukuqeda umsindo ogelezayo

2)Lezi zisetshenziselwa ukulingisa isistimu

3）.Kuhlanganisa umugqa kanye nokuzinza kwenzuzo ephezulu.

4)Inokuvikeleka okuphezulu emsindweni kazibuthe

5)Ngokuyisebenzisa, ungagwema umsindo.

Izicelo zokuhlukaniswa kwe-capacitive zifaka phakathi ukutholwa kwedatha, izingxenye zesixhumi esibonakalayo, ukuqapha kwesiguli, i-electroencephalography, ne-electrocardiogram.
