Ukuhlaziywa kwepharamitha nokukalwa kwama-MOSFET

Kunezinhlobo eziningi zamapharamitha ayinhloko weI-MOSFET, equkethe i-DC yamanje, amapharamitha amanje e-AC kanye nemingcele yomkhawulo, kodwa uhlelo lokusebenza olujwayelekile ludinga kuphela ukukhathalela lezi zinhlaka eziyisisekelo ezilandelayo: isimo sokugcwaliswa komthombo wamanje wokuvuza we-IDSS pinch-off voltage Up, i-transconductance gm, i-voltage yokuhlukana komthombo ovuzayo we-BUDS, amandla amakhulu okukhipha ukulahlekelwa kwe-PDSM kanye ne-IDSM yamanje yomthombo wokuvuza omkhulu.

1.Umthombo wokuvuza ogcwele wamanje

I-IDSS yamanje yomthombo wokukhipha amanzi egcwele isho amandla omthombo wamanzi ku-voltage yesango i-UGS = 0 ekuhlanganeni noma ohlotsheni lokuncipha kwesango elifakwe ungqimba oluvikelwe ama-MOSFET.

2. I-voltage ye-clip-off

I-pinch-off voltage UP isho i-voltage yesango esebenza ku-junction noma uhlobo lokuncipha kwesango elifakwe ungqimbaI-MOSFETlokho kwenza i-drain-source ivele inqanyulwe. Thola ukuthi i-IDSS ne-UP zisho ukuthini ngempela.

3. Vula i-voltage

I-voltage evulayo i-UT isho amandla kagesi wesango asebenza ku-MOSFET esangweni eliqinisiwe ukuze uxhumano lomthombo wokukhipha amanzi luvele luvulwe. Thola ukuthi i-UT isho ukuthini ngempela.

4.Ukuqondisa okuphambanayo

I-transguide gm isetshenziselwa ukukhombisa ikhono le-voltage yomthombo wesango ukulawula i-drain current, okungukuthi, isilinganiso phakathi kokushintshwa kwe-drain current kanye nokushintshwa kwe-voltage yomthombo wesango.

5, Ukulahlekelwa okukhulu kwamandla okukhiphayor

Amandla amakhulu okukhipha ukulahlekelwa ayingxenye yepharamitha yomkhawulo, okusho ukuthi umkhawulo wamandla olahleko angavunyelwa uma ukusebenza kweI-MOSFETijwayelekile futhi ayithinteki. Uma sisebenzisa i-MOSFET, ukulahleka kwayo kokusebenza kufanele kube ngaphansi kune-PDSM kanye nenani elithile.

6, Umthombo omkhulu wokuvuza wamanje

Umthamo omkhulu wamanje we-drain-source current, i-IDSM, nawo uyipharamitha ekhawula, okusho ukuthi inani eliphezulu lamanje elivunyelwe ukudlula phakathi kwe-drain kanye nomthombo we-MOSFET ngesikhathi sokusebenza okuvamile, futhi akumele lidlule lapho i-MOSFET isebenza.

u- olukey usephenduke enye yama-ejenti ahamba phambili futhi akhula ngokushesha e-Asia ngokuthuthukiswa kwemakethe okusebenzayo nokuhlanganiswa kwezinsiza okusebenzayo, futhi ukuba i-ejenti ebaluleke kakhulu emhlabeni kuwumgomo ofanayo we- olukey.
