Chii chandingaite kugadzirisa MOSFET yangu iri kupisa zvakanyanya?

Magetsi emagetsi emagetsi, kana magetsi emagetsi emagetsi mumunda wepropulsion, anoshandisa zvisingadzivisikiMOSFETs, ayo ari emarudzi akawanda uye ane mabasa akawanda. Pakushandura magetsi emagetsi kana maapplication application, ndezvemusikirwo kushandisa shanduko yayo.

Pasinei neN-mhando kana P-mhandoMOSFET, musimboti wacho wakangofanana, MOSFET inowedzerwa kugedhi rekuguma kwechisungo chezvino kuti ridzore divi rekubuda kwemvura yazvino, MOSFET mudziyo unodzorwa nevoltage unobva pane ikozvino yakawedzerwa kugedhi pa. mashandisirwo ehunhu hwechishandiso, haaite kuchinjika senge transistor nekuda kwechigadziko chazvino chinokonzerwa nechaji yekuchengetera mhedzisiro, uye nekudaro, mukuchinja kwekushandisa, iyo MOSFET yekuchinja chiyero inofanira kukurumidza kupfuura iyo. transistor. Chiyero chekuchinja chinofanira kukurumidza kupfuura matatu.

MOSFETdiki-ikozvino kupisa zvinokonzera

1, musimboti wedunhu redambudziko nderekurega MOSFET ichishanda mumutsara mamiriro ekushanda, kwete mumamiriro ekuchinja. Izvi zvakare chikonzero chekupisa kweMOSFET. Kana iyo N-MOS ichichinja, G-level inoshanda voltage pane iyo switching simba inopa mashoma V, kuitira kuti inyatso batidzwa nekudzima, P-MOS ndiyo imwe nzira yakapoteredza. Kwete zvachose uye kurasikirwa kwakakura zvakanyanya zvichikonzera kubuda kwesimba kupera, iyo yakaenzana yedunhu DC hunhu impedance yakakura, kurasikirwa kunowedzera, saka U * Ini zvakare yakawedzerwa, kupera kunomiririra kupisa. Iyi zvakare yakanyanya kudziviswa isiriyo dhizaini chirongwa chekudzora redunhu.

2, iyo frequency yakanyanya kukwirira, kunyanya dzimwe nguva yakawandisa yekutsvaga vhoriyamu yakakwana, zvichikonzera kuwedzera frequency, MOSFET pakuwedzera kwekushandisa, saka kupisa kwakawedzerawo.

3, haina kuita yakakwana kupisa kusarudzika dhizaini dhizaini, yazvino yakakwira zvakanyanya, MOSFET kushivirira kukosha kwazvino, kazhinji inofanirwa kuchengetedza kunaka kwekupisa kunogona kuitwa. Naizvozvo, ID yakadzikira pane yakakwira ikozvino, inogonawo kupisa zvakanyanya, inofanirwa kukwana kubatsira kunyura kwekupisa.

4, kusarudzwa kweMOSFET modhi hakuna kunaka, simba rekubuda harina chokwadi, kuramba kweMOSFET hakufungidzirwe, zvichikonzera kuwedzera kweiyo switching hunhu impedance.

MOSFET diki yazvino kudziyisa yakanyanya kukomba nzira yekugadzirisa?
