AMC1200SDUBR 100% Nyowani & Yekutanga Isolation Amplifier 1 Circuit Differential 8-SOP

Pane nzira nhatu dzekugadzira dzinoshandiswa kuzvimiririra amplifiers, kusanganisira:

1. Transformer kuparadzaniswa

Mhando iyi yekuzviparadzanisa nevamwe inoshandisa ingave PWM kana frequency-modulated masaini.Mukati, iyo amplifier inosanganisira makumi maviri KHz oscillator, rectifier, sefa, uye transformer yekugonesa imwe neimwe nhanho yekuzviparadzanisa nevamwe.

1).Iyo rectifier inoshandiswa sekuisa kune iyo huru yekushanda amplifier.

2).Batanidza transformer kune magetsi.

3).Iyo oscillator inoshandiswa sekuisa kwechipiri chekushanda amplifier.

4) .LPF inoshandiswa kubvisa zvikamu zvemamwe mafrequency.

5).Zvakanakira zvekuzviparadzanisa neshanduko zvinonyanya zvinosanganisira yakakwira CMRR, mutsara uye iko kurongeka.

Zvikumbiro zvekuzviparadzanisa ne transformer zvinosanganisirazvokurapa, nuclearuye kushandiswa kwemaindasitiri.

2. Optical kuparadzaniswa

Mukuzviparadzanisa nevamwe, iyo l siginecha inogona kuchinjwa kubva kubhaibheri chiratidzo kuenda kune yekuona chiratidzo ne LED kuti ienderere mberi nekugadzirisa.Muchiitiko ichi, dunhu remurwere ndiro dunhu rekupinza, nepo kubuda kwedunhu kunogona kuumbwa kubva kune phototransistor.Aya maseketi anofambiswa nemabhatiri.Iyo i/p yedunhu inoshandura chiratidzo kuita mwenje, uye o/p dunhu rinoshandura mwenje kudzoka kuita chiratidzo.

Zvakanakira zve optical isolation zvinosanganisira:

1).Nekuishandisa, tinogona kuwana amplitude uye mbishi frequency.

2).Iyo yakabatana optically isina modulator kana demodulator.

3).Inovandudza kuchengetedzwa kwevarwere.

Zvishandiso zveshanduko yekuzviparadzanisa nevamwe zvinosanganisira maindasitiri process control, kutora data, biomedical kuyerwa, kutarisa kwemurwere, interface zvikamu, bvunzo michina, SCR control, nezvimwe.

3. Capacitor kuparadzaniswa

1).Inoshandisa frequency modulation uye dijitari encoding yekupinza voltage.

2）.Iyo yekupinza voltage inogona kuchinjirwa kune hama yekuchaji pane switching capacitor.

3）.Inosanganisira masekete akadai se modulator uye demodulator.

4）.Zviratidzo zvinotumirwa kuburikidza nekusiyanisa capacitive zvipingamupinyi.

5）.Kune mapato maviri, ipa zvakasiyana.

Zvakanakira capacitive isolation zvinosanganisira:

1）.Kuzviparadzanisa nevamwe uku kunogona kushandiswa kubvisa ripple ruzha

2）.Aya anoshandiswa kutevedzera sisitimu

3）.Inosanganisira mutsara uye yakakwirira kuwana kugadzikana.

4）.Iyo ine yakanyanya kusadzivirirwa kune magineti ruzha

5）.Nekuishandisa, unogona kudzivirira ruzha.

Zvikumbiro zve capacitive isolation zvinosanganisira kutora data, interface zvikamu, kutarisa kwemurwere, electroencephalography, uye electrocardiogram.
