I. Ibisobanuro bya MOSFET
Nka voltage itwarwa, ibikoresho-bigezweho, MOSFETS ufite umubare munini wibisabwa mumuzunguruko, cyane cyane sisitemu yimbaraga. MODFET yumubiri wa MOSFET, izwi kandi nka parasitike ya diode, ntabwo iboneka muri lithographie yumuzunguruko uhuriweho, ariko iboneka mubikoresho bitandukanye bya MOSFET, bitanga uburinzi bwinyuma kandi bikomeza mugihe iyo bitwarwa numuyaga mwinshi kandi mugihe imitwaro ya inductive ihari.
Bitewe nuko iyi diode ihari, igikoresho cya MOSFET ntigishobora kugaragara gusa guhinduranya mumuzunguruko, nko mumuzunguruko wumuriro aho kwishyuza birangiye, ingufu zivanwaho kandi bateri igasubira hanze, mubisanzwe nigisubizo kidakenewe.
Igisubizo rusange ni ukongeramo diode inyuma kugirango wirinde amashanyarazi ahindagurika, ariko ibiranga diode bigena ko hakenewe kugabanuka kumashanyarazi ya 0.6 ~ 1V, bikavamo kubyara ubushyuhe bukabije kumuyaga mwinshi mugihe bitera imyanda. y'ingufu no kugabanya ingufu muri rusange. Ubundi buryo ni ugushyira MOSFET inyuma-yinyuma, ukoresheje imbaraga nke-zirwanya MOSFET kugirango ugere kubikorwa byingufu.
Twabibutsa ko nyuma yo gutwarwa, MOSFET idafite icyerekezo, bityo rero nyuma yo gutwarwa nigitutu, ihwanye nu nsinga, irwanya gusa, nta na voltage igabanuka kuri leta, ubusanzwe yuzuyemo imbaraga zo kurwanya miliohms nkeya kugezamiliohms ku gihe, kandi ntabwo ari icyerekezo, kwemerera DC na AC imbaraga kurengana.
II. Ibiranga MOSFETS
1, MOSFET nigikoresho kigenzurwa na voltage, nta cyiciro cyo gusunika gikenewe kugirango utware amashanyarazi menshi;
2 resistance Kurwanya cyane kwinjiza;
3, ibikorwa byinshi byinshyi, umuvuduko mwinshi, igihombo gito
4, AC yorohewe cyane impedance, urusaku ruke.
5 、Gukoresha byinshi kubangikanye, ongera ibisohoka bigezweho
Icya kabiri, ikoreshwa rya MOSFETs murwego rwo kwirinda
1, kugirango tumenye neza ko MOSFET ikoreshwa neza, mugushushanya kumurongo, ntigomba kurenza umuyoboro wogukwirakwiza amashanyarazi, ingufu zidasanzwe ziva mumashanyarazi, amarembo yinkomoko yumuryango hamwe nibindi bipimo ntarengwa.
2, ubwoko butandukanye bwa MOSFETs ikoreshwa, igombakuba muri ukurikije kubogama gusabwa kugera kumuzunguruko, kugirango ukurikize polarite ya MOSFET offset.
3. Mugihe ushyiraho MOSFET, witondere aho ushyira kugirango wirinde hafi yubushyuhe. Kugirango wirinde kunyeganyega kw'ibikoresho, igikonoshwa kigomba gukomera; kunama pin iyobora bigomba gukorwa kurenza ubunini bwumuzi wa 5mm kugirango wirinde pin kunama no gutemba.
4, kubera inzitizi nyinshi zinjira cyane, MOSFETs igomba kugabanywa kuri pin mugihe cyo gutwara no kubika, hanyuma igapakirwa hamwe nicyuma gikingira ibyuma kugirango hirindwe ko amarembo ashobora kumeneka.
5. Irembo rya voltage yumuryango MOSFETs ntishobora guhindurwa kandi irashobora kubikwa muburyo bwumuzunguruko, ariko kurwanya kwinjiza MOSFETs yinjizwamo amarembo ni menshi cyane mugihe bidakoreshejwe, bityo buri electrode igomba kuba izunguruka mugihe gito. Mugihe ugurisha-irembo MOSFETs, ukurikize gahunda yisoko-imiyoboro-irembo, hamwe nugurisha ufite umuriro.
Kugirango umenye neza imikoreshereze ya MOSFETs, ugomba kumva neza neza ibiranga MOSFETS hamwe ningamba zafatwa mugukoresha inzira, nizere ko incamake yavuzwe haruguru izagufasha.
