I le fa'aeletonika ma le fa'ainisinia, o le fa'aogaina oMOSFETs(metal-oxide-semiconductor field-effect transistors) ua avea ma mea taua i le faʻaleleia atili o le faʻatinoga o faʻatonuga eletise eletise (ESR). O lenei tusiga o le a suʻesuʻeina pe faʻafefea ona galue MOSFET ma pe faʻafefea ona latou faia se sao taua i le faʻatonutonuina o le saoasaoa faaeletonika.
Le mataupu faavae galue o le MOSFET:
O le MOSFET o se masini semiconductor e liliu ai le tafe o le eletise i luga pe tape e ala i le pulea voltage. I le faʻatonutonuina o le saoasaoa faʻaeletoroni, o loʻo faʻaaogaina MOSFET e fai ma sui elemene e faʻatonutonu ai le tafe o loʻo i ai nei i le afi, faʻatagaina le pulea saʻo o le saoasaoa o le afi.
Fa'aogaina o MOSFET i fa'atonu fa'aeletoroni fa'atonu:
O le faʻaaogaina o lona saoasaoa faʻaleleia lelei ma le lelei o le pulea o le taimi nei, MOSFETs e faʻaaogaina lautele i le eletise eletise eletise i le PWM (Pulse Width Modulation). O lenei talosaga e faʻamautinoa ai e mafai e le afi ona faʻagaioia ma le lelei i lalo o tulaga eseese o uta.
Filifili le MOSFET sa'o:
Pe a fa'atulagaina se fa'atonu fa'aeletonika, o le filifilia o le MOSFET sa'o e taua tele. Fa'ata'ita'iga e tatau ona mafaufau i ai e aofia ai le maualuga o alavai-punavai voli (V_DS), aupito maualuga fa'aauau pea le tafe (I_D), suiga vave, ma le fa'aogaina o le vevela.

Fa'ateteleina le fa'atinoga o le fa'atonu fa'aeletoroni saosaoa:
E ala i le faʻaleleia atili o tulaga faʻaogaina ma le faʻasologa o le MOSFET, o le faʻatinoga o le faʻatonuina o le saoasaoa eletise e mafai ona faʻaleleia atili. E aofia ai le faʻamautinoaina o le malulu lelei, filifilia o le taʻavale taʻavale talafeagai, ma faʻamautinoa o isi vaega o le matagaluega e mafai foi ona ausia manaʻoga faʻatinoga.
