AMC1200SDUBR 100% Chatsopano & Choyambirira Chodzipatula Amplifier 1 Differential Circuit 8-SOP

Pali njira zitatu zamapangidwe zomwe zimagwiritsidwa ntchito pakudzipatula amplifiers, kuphatikiza:

1. Transformer kudzipatula

Kudzipatula kwamtunduwu kumagwiritsa ntchito ma PWM kapena ma frequency modulated sign.Mkati, amplifier imaphatikizapo 20 KHz oscillator, rectifier, fyuluta, ndi thiransifoma kuti igwiritse ntchito gawo lililonse lodzipatula.

1).Chowongoleracho chimagwiritsidwa ntchito ngati cholowetsa ku amplifier yayikulu.

2).Lumikizani thiransifoma ku magetsi.

3).Oscillator imagwiritsidwa ntchito ngati cholumikizira cha amplifier yachiwiri.

4) .LPF imagwiritsidwa ntchito kuchotsa zigawo za ma frequency ena.

5).Ubwino wa kudzipatula kwa thiransifoma makamaka umaphatikizapo CMRR yapamwamba, mzere komanso kulondola.

Mapulogalamu odzipatula a transformer akuphatikizapozachipatala, nyukiliyandi ntchito mafakitale.

2. Optical kudzipatula

Pakudzipatula uku, chizindikiro cha l chikhoza kusinthidwa kuchoka pa chizindikiro cha chilengedwe kupita ku chizindikiro cha kuwala ndi LED kuti ipitirire.Pankhaniyi, dera la odwala ndilo gawo lothandizira, pamene gawo lotulutsa likhoza kupangidwa kuchokera ku phototransistor.Zozungulira izi zimayendetsedwa ndi mabatire.Dera la i/p limasintha siginecha kukhala kuwala, ndipo dera la o/p limasinthanso kuwala kukhala chizindikiro.

Ubwino wa optical isolation ndi monga:

1).Pogwiritsa ntchito, tikhoza kupeza matalikidwe ndi mafupipafupi.

2).Imalumikizidwa bwino popanda modulator kapena demodulator.

3).Imawongolera chitetezo cha odwala.

Kugwiritsa ntchito kudzipatula kwa thiransifoma kumaphatikizapo kuwongolera njira zamafakitale, kupeza deta, kuyeza kwachilengedwe, kuwunika kwa odwala, mawonekedwe a mawonekedwe, zida zoyesera, kuwongolera kwa SCR, ndi zina zambiri.

3. Kudzipatula kwa capacitor

1).Imagwiritsa ntchito ma frequency modulation ndi encoding ya digito yamagetsi olowera.

2）.Mphamvu yolowera imatha kusinthidwa kukhala mtengo wachibale pa switching capacitor.

3）.Zimaphatikizapo mabwalo monga modulator ndi demodulator.

4）.Zizindikiro zimatumizidwa kudzera muzotchinga za capacitive zosiyana.

5）.Kwa onse awiri, perekani mosiyana.

Ubwino wa capacitive kudzipatula ndi:

1）.Kudzipatula kumeneku kungagwiritsidwe ntchito kuthetsa phokoso la phokoso

2）.Izi zikugwiritsidwa ntchito kutengera ndondomekoyi

3）.Zimaphatikizapo mzere ndi kukhazikika kwapamwamba.

4）.Ili ndi chitetezo chokwanira ku phokoso la maginito

5）.Pogwiritsa ntchito, mutha kupewa phokoso.

Kufunsira kwa capacitive kudzipatula kumaphatikizapo kupeza deta, mawonekedwe a mawonekedwe, kuyang'anira odwala, electroencephalography, ndi electrocardiogram.
