Mạch Rc Bậc Nhất – Điện Tử/Mạch Điện Điện Tử/Mạch Rc Nối Tiếp

RC Integrator ndi mndandanda wolumikizidwa wa RC womwe umatulutsa chizindikiro chofanana ndi kuphatikiza masamu.

Mukuwona: Circuit rc

Kwa chophatikizira cha RC chophatikizira, cholowetsacho chimalumikizidwa ndi chopinga pomwe mphamvu yotulutsa imatengedwa kuchokera ku capacitor yomwe ili yosiyana ndendende ndi RC . Capacitor imalipira pamene kulowetsa kuli kwakukulu ndipo kumatulutsa pamene kulowetsako kuli kochepa.

Mu Electronics, mabwalo oyambira a resistor-capacitor (RC) ali ndi ntchito zosiyanasiyana ndikugwiritsa ntchito kuchokera kumayendedwe oyambira / otulutsa kupita kumayendedwe apamwamba kwambiri. Dera la RC lomwe lili ndi zigawo ziwiri likhoza kuwoneka losavuta, koma malingana ndi mtundu ndi kuchuluka kwa chizindikiro cholowetsamo, khalidwe ndi kuyankha kwa dera lofunikira la RC likhoza kukhala losiyana kwambiri.

Dera la Passive RC silinanso kanthu koma chotsutsa pamndandanda wokhala ndi capacitor ndi chopinga chokhazikika pamndandanda wokhala ndi capacitor yemwe kukana kwake kumadalira kumachepera pomwe ma frequency pama mbale ake akuwonjezeka. Chifukwa chake, pamafupipafupi otsika, mphamvu, Xc ya capacitor ndi yayikulu pomwe pamayendedwe apamwamba, mphamvu ya capacitor imakhala yotsika ndi mawonekedwe amtundu wa Xc = 1 / (2πƒC).

Ngati chizindikiro cholowetsamo ndi sine wave, RC Integrator imangochita ngati fyuluta yotsika yotsika (LPF) pa cutoff yake ndi cutoff kapena ngodya pafupipafupi yofanana ndi nthawi ya RC nthawi zonse ( tau, τ ). Chifukwa chake, ikayendetsedwa ndi mafunde oyera a sine, RC Integrator imakhala ngati fyuluta yotsika pang’ono yomwe imachepetsa kutulutsa kwake pamwamba pa ma frequency odulidwa.

Monga tawonera kale, nthawi ya RC nthawi zonse imasonyeza mgwirizano pakati pa kukana ndi mphamvu pakapita nthawi ndi nthawi, mumasekondi, molingana ndi kukana, R, ndi capacitance C.

Choncho, malipiro kapena kutulutsa kumadalira nthawi yokhazikika RC, τ = RC . Ganizirani dera lomwe lili pansipa.

Integral Circuit RC

Kwa chophatikizira cha RC, chizindikiro cholowera chimayikidwa pa chotsutsa ndi zomwe zimatengedwa kudzera pa capacitor, ndiye VOUT ikufanana ndi VC. Popeza capacitor ndi chinthu chodalira pafupipafupi, kuchuluka kwa ndalama zomwe zimakhazikitsidwa pama mbale ndizofanana ndi gawo lanthawi yapano. Ndiko kuti, zimatengera nthawi yochuluka kuti capacitor iwononge mokwanira chifukwa capacitor sangathe kulipira nthawi yomweyo, koma mowonjezereka.

Chifukwa chake, capacitor pano ikhoza kulembedwa motere:

Zomwe zili pamwambazi za iC = Cx(dVc / dt) zitha kuwonetsedwanso ngati kusintha kwanthawi yomweyo, Q pakapita nthawi kumapereka ma equation awa: iC = dQ / dt pomwe mtengo wogulitsa Q = C x Vc , chomwe ndi capacitance times voltage.

Mlingo womwe capacitor amalipira (kapena kutulutsa) umagwirizana ndi kukana nthawi zonse komanso mphamvu ya dera. Chifukwa chake nthawi yokhazikika ya chophatikiza cha RC ndi nthawi yofanana ndi zomwe zimapangidwa ndi R ndi C.

Popeza capacitance ndi yofanana ndi Q/Vc kumene kulipiritsa, Q ndikuyenda kwapano (i) pakapita nthawi
