I-AMC1200SDUBR 100% Entsha & neyoqobo yoKwahlula Iamplifier 1 Umahluko weSekethe 8-SOP

Kukho iindlela ezintathu zoyilo ezisetyenziselwa i-amplifiers yodwa, kubandakanya:

1. Ukwahlulwa kweTransformer

Olu hlobo lokwahlula lusebenzisa nokuba yi-PWM okanye imiqondiso emodareyithwa rhoqo.Ngaphakathi, i-amplifier ibandakanya i-oscillator ye-20 KHz, i-rectifier, filter, kunye ne-transformer ukunika amandla isigaba ngasinye sokuzihlukanisa.

1).Isilungisi sisetyenziswa njengegalelo kwi-amplifier engundoqo esebenzayo.

2).Xhuma i-transformer kunikezelo lwamandla.

3).I-oscillator isetyenziswe njengegalelo le-amplifier yokusebenza yesibini.

4) .I-LPF isetyenziselwa ukususa amacandelo amanye ama-frequencies.

5).Iingenelo zokuhlukaniswa kwe-transformer ikakhulu zibandakanya i-CMRR ephezulu, umgca kunye nokuchaneka.

Izicelo zokwahlulwa kwe-transformer zibandakanyaezonyango, zenyukliyakunye nezicelo zoshishino.

2. Ukwahlukaniswa kwamehlo

Kule yodwa, i-signal ye-l ingatshintshwa ukusuka kwi-biological signal ukuya kwi-optical signal yi-LED yokuqhubela phambili.Kule meko, isiphaluka sesigulana yisekethe yegalelo, ngelixa isiphaluka semveliso sinokuqulunqwa kwi-phototransistor.Ezi sekethe zinikwa amandla ziibhetri.Isekethe ye-i/p iguqula isignali ibe kukukhanya, kwaye isiphaluka se-o/p siguqula ukukhanya kwakhona sibe ngumqondiso.

Izinto eziluncedo zokwahlulwa kwamehlo ziquka:

1).Ngokuyisebenzisa, sinokufumana i-amplitude kunye ne-frequency ekrwada.

2).Idityaniswe ngokubonakalayo ngaphandle kwemodyuli okanye idemodulator.

3).Iphucula ukhuseleko lwesigulane.

Izicelo zokuhlukaniswa kwe-transformer zibandakanya ulawulo lwenkqubo yoshishino, ukufumana idatha, ukulinganisa kwe-biomedical, ukubeka iliso kwesigulane, amacandelo e-interface, izixhobo zokuvavanya, ulawulo lwe-SCR, njl.

3. Ukwahlukaniswa kweCapacitor

1).Isebenzisa ukumodareyitha rhoqo kunye ne-encoding yedijithali yombane wokufaka.

2I-voltage yegalelo ingatshintshwa kwintlawulo ehambelanayo kwi-capacitor yokutshintsha.

3）.Ibandakanya iisekethe ezifana nemodyuli kunye nedemodulator.

4）.Iimpawu zithunyelwa ngokusebenzisa izithintelo ezahlukeneyo ze-capacitive.

5）.Kuwo omabini amaqela, bonelela ngokwahlukeneyo.

Izinto eziluncedo zokwahlukaniswa kwe-capacitive ziquka:

1Oku kwahlula kungasetyenziselwa ukuphelisa ingxolo yokukhala

2Ezi zisetyenziselwa ukulinganisa inkqubo

3）.Ibandakanya umgca kunye nokuzinza okuphezulu.

4）.Inokhuselo oluphezulu kwingxolo yamagnetic

5）.Ngokuyisebenzisa, unokuphepha ingxolo.

Izicelo ze-capacitive isolation ziquka ukufumana idatha, amacandelo e-interface, ukubeka iliso kwesigulane, i-electroencephalography, kunye ne-electrocardiogram.
