Embonini ye-electronics kanye ne-automation, ukusetshenziswa kweAma-MOSFET(i-metal-oxide-semiconductor field-effect transistors) isibe yisici esibalulekile ekuthuthukiseni ukusebenza kwezilawuli ze-electronic speed (ESR). Lesi sihloko sizohlola ukuthi ama-MOSFET asebenza kanjani nokuthi abamba iqhaza elibalulekile ekulawuleni isivinini ngogesi.
Umgomo oyisisekelo wokusebenza we-MOSFET:
I-MOSFET iyithuluzi le-semiconductor elivula noma livale ukugeleza kwamandla kagesi ngokusebenzisa ukulawulwa kwamandla kagesi. Kuzilawuli zejubane lika-elekthronikhi, ama-MOSFET asetshenziswa njengezinto ezishintshayo ukuze alawule ukugeleza kwamanje kumotho, okuvumela ukulawulwa okunembile kwejubane lemoto.
Izicelo zama-MOSFET kuzilawuli zejubane zikagesi:
Isebenzisa isivinini sayo esihle kakhulu sokushintsha namandla asebenzayo okulawula amanje, ama-MOSFET asetshenziswa kabanzi kuzilawuli zejubane zikagesi kumasekethe e-PWM (Pulse Width Modulation). Lolu hlelo lokusebenza luqinisekisa ukuthi injini ingasebenza ngokuzinza nangempumelelo ngaphansi kwezimo ezihlukahlukene zomthwalo.
Khetha i-MOSFET efanele:
Lapho uklama isilawuli sesivinini sikagesi, ukukhetha i-MOSFET efanele kubalulekile. Amapharamitha okufanele acatshangelwe ahlanganisa i-drain-source voltage (V_DS), umthamo omkhulu wokuvuza oqhubekayo (I_D), isivinini sokushintsha, nokusebenza okushisayo.
Okulandelayo izinombolo zengxenye yohlelo lokusebenza lwe-WINSOK MOSFETs kuzilawuli zejubane zikagesi:

Lungiselela ukusebenza kwesilawuli sesivinini sika-elekthronikhi:
Ngokulungiselela izimo zokusebenza kanye nokwakheka kwesekethe ye-MOSFET, ukusebenza kwesilawuli sesivinini sikagesi kungathuthukiswa. Lokhu kuhlanganisa ukuqinisekisa ukupholisa okwanele, ukukhetha isekethe yomshayeli efanele, kanye nokuqinisekisa ukuthi ezinye izingxenye zesekethe nazo zingahlangabezana nezidingo zokusebenza.
