Iyo diode yemuviri (iyo inowanzongotaurwa nezvayo seyakajairika diode, sezwi“muviri diode”haiwanzo shandiswa mumamiriro enguva dzose uye inogona kureva chimiro kana chimiro che diode pachayo; zvisinei, nokuda kwechinangwa ichi, tinofungidzira kuti inoreva diode yakajairwa) uye MOSFET (Metal Oxide Semiconductor Field Effect Transistor) inosiyana zvakanyanya mune akati wandei. Pazasi pane ongororo yakadzama yekusiyana kwavo:
1. Basic Definitions uye Structures
- Diode: Diode mudziyo wesemiconductor une maelectrode maviri, akaumbwa neP-type uye N-type semiconductors, achigadzira PN junction. Inongobvumira ikozvino kuyerera kubva kune yakanaka kuenda kune yakashata side (mberi bias) ichivharira reverse kuyerera (reverse bias).
- MOSFET: A MOSFET chishandiso chetatu-terminal semiconductor chinoshandisa magetsi emumunda kudzora iripo. Iyo ine gedhi (G), tsime (S), uye dhiraivha (D). Ikozvino pakati pechitubu uye drain inodzorwa negedhi voltage.
2. Kushanda Nheyo
- Diode: Nheyo yekushanda ye diode yakavakirwa pane unidirectional conductivity yePN junction. Pasi pekurerekera mberi, vatakuri (maburi nemaerekitironi) vanopararira nepakati pePN junction kuti vagadzire ikozvino; pasi pe reverse bias, chinogona chipingamupinyi chinogadzirwa, kudzivirira kuyerera kwezvino.
- MOSFET: Iyo misimboti yekushanda yeMOSFET yakavakirwa pamagetsi emunda maitiro. Kana gedhi remagetsi richichinja, rinogadzira chiteshi chekufambisa (N-channel kana P-channel) pamusoro peiyo semiconductor pasi pegedhi, ichidzora ikozvino pakati pechitubu uye dhizaini. MOSFETs midziyo inodzorwa nevoltage, ine inobuda ikozvino zvichienderana nekuisa voltage.
3. Maitiro Ekuita
- Diode:
-Inokodzera yakakwirira-frequency uye yakaderera-simba maapplication.
-Ine unidirectional conductivity, ichiita kuti ive chinhu chakakosha mukugadzirisa, kuona, uye voltage regulation circuits.
- Reverse breakdown voltage ndiyo yakakosha parameter uye inofanirwa kutariswa mukugadzira kudzivirira kudzoreredza kuparara nyaya.
- MOSFET:
-Ine yakakwira yekupinza impedance, yakaderera ruzha, yakaderera mashandisiro emagetsi, uye yakanaka yekudziya kugadzikana.
- Inokodzera mahombe-akabatanidzwa maseketi uye magetsi emagetsi.
- MOSFETs yakakamurwa kuita N-chiteshi uye P-chiteshi mhando, imwe neimwe inouya mukusimudzira-modhi uye depletion-modhi mhando.
- Inoratidza yakanaka inogara iripo maitiro, iine yazvino yasara inogara isingachinjike munzvimbo yesaturation.
4. Minda Yekushandisa
- Diode: Inoshandiswa zvakanyanya mumagetsi, kutaurirana, uye magetsi ekupa magetsi, senge mukugadzirisa maseketi, voltage regulation circuits, uye matunhu ekuona.
- MOSFET: Inotora basa rakakosha mumasekete akabatanidzwa, magetsi emagetsi, makomputa, uye kutaurirana, anoshandiswa sekuchinja zvinhu, amplification zvinhu, uye zvinhu zvekutyaira.
5. Mhedziso
Diodes uye MOSFETs anosiyana mukutsanangura kwavo kwekutanga, zvimiro, misimboti yekushanda, hunhu hwekuita, uye minda yekushandisa. Madhiodhi anoita basa rakakosha mukugadzirisa uye kudzorwa kwemagetsi nekuda kwekuita kwavo unidirectional, nepo maMOSFET achishandiswa zvakanyanya mumaseketi akabatanidzwa uye magetsi emagetsi nekuda kwekukwirisa kwavo kupinza, ruzha rushoma, uye kushomeka kwesimba. Zvikamu zvese zviri zviviri zvakakosha kune tekinoroji yemazuva ano yemagetsi, imwe neimwe ichipa zvayakanakira.
