AMC1200SDUBR 100% Gishya & Umwimerere wo Kwigunga Amplifier 1 Umuzenguruko Utandukanye 8-SOP

Hariho uburyo butatu bwo gushushanya bukoreshwa mukwiyongera kwinyongera, harimo:

1. Guhindura akato

Ubu bwoko bwo kwigunga bukoresha PWM cyangwa ibimenyetso byahinduwe.Imbere, amplifier ikubiyemo 20 KHz oscillator, ikosora, iyungurura, na transformateur kugirango imbaraga buri cyiciro cyo kwigunga.

1).Ikosora ikoreshwa nkiyinjiza mubikorwa nyamukuru byongera imbaraga.

2).Huza transformateur kumashanyarazi.

3).Oscillator ikoreshwa nkiyinjiza rya kabiri ikora amplifier.

4) .LPF ikoreshwa mugukuraho ibice byindi mirongo.

5).Ibyiza bya transformateur kwigunga cyane harimo CMRR yo hejuru, umurongo nukuri.

Gusaba guhindura transformateur harimoubuvuzi, kirimbuzin'inganda zikoreshwa.

2. Kwigunga neza

Muri uku kwigunga, ikimenyetso cya l gishobora guhinduka kuva mubimenyetso byibinyabuzima bikagera ku kimenyetso cyiza na LED kugirango gikorwe neza.Muri iki kibazo, uruzinduko rwabarwayi nuruzinduko rwinjira, mugihe uruzinduko rushobora gushingwa kuva kuri Phototransistor.Iyi miyoboro ikoreshwa na bateri.Inzira ya i / p ihindura ibimenyetso mumucyo, naho o / p umuzenguruko uhindura urumuri mubimenyetso.

Ibyiza byo kwigunga neza birimo:

1).Mugukoresha, dushobora kubona amplitude hamwe na frequency frequency.

2).Ihujwe neza idafite modulator cyangwa demodulator.

3).Itezimbere umutekano wumurwayi.

Gushyira mu bikorwa kwigunga kwa transformateur harimo kugenzura ibikorwa byinganda, gushaka amakuru, gupima ibinyabuzima, kugenzura abarwayi, ibice bigize interineti, ibikoresho byo gupima, kugenzura SCR, nibindi.

3. Kwigunga

1).Ikoresha modulisiyo ya modulisiyo hamwe na kodegisi ya digitale yinjiza voltage.

2）.Iyinjiza ya voltage irashobora guhinduka muburyo bwo kwishyurwa kuri capacitori.

3）.Harimo imirongo nka modulator na demodulator.

4）.Ibimenyetso byoherejwe hakoreshejwe inzitizi zitandukanye.

5）.Ku mpande zombi, tanga ukwe.

Ibyiza byo kwigunga kwa capacitive harimo:

1）.Uku kwigunga kurashobora gukoreshwa mugukuraho urusaku rwinshi

2）.Ibi bikoreshwa mukwigana sisitemu

3）.Harimo umurongo no kunguka byinshi.

4）.Ifite ubudahangarwa bukabije ku rusaku rukuruzi

5）.Ukoresheje, urashobora kwirinda urusaku.

Porogaramu zo kwigunga zifite ubushobozi bwo kubona amakuru, ibice bigize interineti, gukurikirana abarwayi, electroencephalography, na electrocardiogram.
